Question

solve for x and y 5x + 4y = 4 and x - 12y = 20​

Answer 1

x = 4 - 4y ÷ by 5

Now;

put the value of x in equation 2

•°• 4 - 4y ÷ 5 - 12 y = 20

4 - 4y - 60y ÷ 5 = 20

4 - 4y - 60y = 100

4 - 64 y = 100

- 64y - 96 = 0

y = - 96/ 64

y = - 1.5

Now ; put the value of y in equation 1

5x + 4 × (- 1.5 ) = 4

5x - 6 = 4

5x = 10

x = 2
