Question

10y-11x=-4 and -2y+3x=4 find x and y​

Answer 1

Answer:

Y

10y−11x=−4

Step 1: Add 11x to both sides.

−11x+10y+11x=−4+11x

10y=11x−4

X

10y−11x=−4

Step 1: Add -10y to both sides.

−11x+10y+−10y=−4+−10y

−11x=−10y−4

Answer 2

Step-by-step explanation:

adding the eqns

10y-11x=-4

-2y+3x=4

we get

8y-8x=0

8y=8x

y=x

hence , 10y-11y=4

-21y=4

y=4/-21

x=y=4/-21
