Answer:

X=11y+4 y= -1/11x + 4/11

Explanation:

Let's solve for x.

8x+4y+24−7x+7y=28

Step 1: Add -24 to both sides.

x+11y+24+−24=28+−24

x+11y=4

Step 2: Add -11y to both sides.

x+11y+−11y=4+−11y

answer: x=−11y+4

Let's solve for y.

8x+4y+24−7x+7y=28

Step 1: Add -24 to both sides.

x+11y+24+−24=28+−24

x+11y=4

Step 2: Add -x to both sides.

x+11y+−x=4+−x

11y=−x+4

Step 3: Divide both sides by 11.

11

11y/11 = - x+4/11

y=-1/11x +4/1
