Answer 2

Answer:

8x+5y =9

+5y =9Subtract 8x both sides we get

+5y =9Subtract 8x both sides we get 5y = 9 – 8x

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =4

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =43x + 2(9 – 8 x)/5) = 4

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =43x + 2(9 – 8 x)/5) = 4 Multiply by 5 we get

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =43x + 2(9 – 8 x)/5) = 4 Multiply by 5 we get 15 x + 18 - 16 x = 20

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =43x + 2(9 – 8 x)/5) = 4 Multiply by 5 we get 15 x + 18 - 16 x = 20 -x = 2

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =43x + 2(9 – 8 x)/5) = 4 Multiply by 5 we get 15 x + 18 - 16 x = 20 -x = 2X = - 2

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =43x + 2(9 – 8 x)/5) = 4 Multiply by 5 we get 15 x + 18 - 16 x = 20 -x = 2X = - 2 Plug this value back in equation (3) we get

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =43x + 2(9 – 8 x)/5) = 4 Multiply by 5 we get 15 x + 18 - 16 x = 20 -x = 2X = - 2 Plug this value back in equation (3) we get Y = (9- 8(-2))/5

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =43x + 2(9 – 8 x)/5) = 4 Multiply by 5 we get 15 x + 18 - 16 x = 20 -x = 2X = - 2 Plug this value back in equation (3) we get Y = (9- 8(-2))/5Y = 25/5

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =43x + 2(9 – 8 x)/5) = 4 Multiply by 5 we get 15 x + 18 - 16 x = 20 -x = 2X = - 2 Plug this value back in equation (3) we get Y = (9- 8(-2))/5Y = 25/5Y = 5

+5y =9Subtract 8x both sides we get 5y = 9 – 8x Divide by 5Y = (9 – 8 x)/5 …(3)Plug this value of y in equation second we get 3x +2y =43x + 2(9 – 8 x)/5) = 4 Multiply by 5 we get 15 x + 18 - 16 x = 20 -x = 2X = - 2 Plug this value back in equation (3) we get Y = (9- 8(-2))/5Y = 25/5Y = 5 Answer is x = -2 and y = 5
