Question

5x+4y=-14 and 3x+6y=6 solve by elimination method

Answer 1

Answer:

X = - 6 and Y = 4

Step-by-step explanation:

5x + 4y = - 14. equation 1

3x + 6y = 6. equation 2

Multiply equation 1 by 6 and equation 2 by 4. Then subtract equation 2 from 1.

30x + 24y = - 84

12x + 24y = 24

- - -

18x + 0. = - 108

=> 18x = - 108

=> x = - 108 / 18

=> x = - 6

Plug in x = - 6 in equation 2 and solve for y

3x + 6y = 6

=> 3×(-6) + 6y = 6

=> - 18 + 6y = 6

=> 6y = 18 + 6

=> 6y = 24

=> y = 4

Hope this will be helpful to you!!!
