The Brainliest Answer!

(Solving by elimination method)

5x - 6y = 8 ------- (1) * 3

-15x + 7y = 9 ------(2) * 1

∴ 15x - 18y = 24

-15x + 7y = 9 Adding both the

__________________

∴ -11y = 33

∴

Putting y = -3 in equation (1)

∴5x -6*(-3) = 8

∴5x +18 = 8

∴5x = 8 - 18

∴5x = -10

∴

Thus. solution of pair of linear equations in two variables is (x,y) = (-2,-3)

7y - 15x=9 ..........(2) × -1

solve the both equations

15x - 18y = 24

15x - 7y = -9

--------------------

-11y = 33

y = -3

substitute y value in eq(1)

5x + 18 =8

5x = -10

x = -10
