1. 5x+2y= 8
Correct answer: -2/5y + 8/5
Add -2y to both sides.
5x+ 2y +-2y = 8+ -2y
5x = -2y + 8
Divide both sides by 5
5x/5 = -2y +8/5
2. Y=3x - 7
Correct answer: 1/3y+ 7/3
Flip the equation
3x- 7=y
Add both sides by 7
3x -7 +7 =y+7
3x = y+7
Divide both sides by 3
3x/3= y+7/3
Hope I get brainlist this took a while.
