Rearrange this equation 5x+3y=8x-7y so that all x terms are on one side and all y terms are on the other: 10y 5x+3y=8x-7y => 10y = 3x, and x = ---------- 3
1. Subtract 5x from both sides. 3y=8x-7y-5x 2. Simplify 8x-7y-5x to 3x-7y 3y=3x-7y 3. Add 7y to both sides 3y+7y=3x 4. Simplify 3y+7y to 10y 10y=3x 5. Divide both sides by 3 10y/3=x 6. Switch sides x=10y/3
