2x - 3y = 50; 7x + 8y = -10

Answer 1

See the picture and u will get the answer

Answer 2

x=10

y=-10

Explanation:

multiply first row by 7

14x−21y=350

​7x+8y=−10

multiply second row by 2

14x−21y=350

​14x+16y=−20

subtract the first row by the second row

−37y=370

solve for y

y=−10

substitute y=-10

14x−21×−10=350

solve for x

x=10

and thats your answer

x=10

y=-10
