x+15=85
Answered by robby
x + 15 = 85

- 15 -15 (subtract 15 from both sides of equation to get x alone and keep equation equal.)
x=70

4y + 5x = -7
divide everything by 4 to get y alone
4y/4 + 5x/4 = -7/4
y + 5x/4 = -7/4
subtract 5x/4 from both sides of equation
y +5x/4 = -7/4
-5x/4 -5x-4
________________
y = -5x -7 / 4

-5x - 7
