solve the equation for y
4y+5x= -7
I came up with this is, is it right?
y=-5x/4+4
3 answers
x+15=85
x + 15 = 85
- 15 -15 (subtract 15 from both sides of equation to get x alone and keep equation equal.)
x=70
- 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
