Question

x(-1/2)-4(-2/y)=(7/-8) find x and y​

Answer 1

Answer:

Step-by-step explanation:

Solve for x

Step 1: Multiply both sides by 2y

-xy + 16 = -7y/4

Step 2: Multiply both sides by 4

-4xy + 64 = -7y

Step 3: add -64 to both sides

-4xy + 64 - 64 = -7y + ( -64)

-4xy = -7y - 6

Step 4: Divide both sides by -4y

-4xy/-4y = -7y-64/-4y

x = -7y -64/-4y(ans)
