solve the equation for y
4y+5x= -7
I came up with this is, is it right?
y=-5x/4+4
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
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

To solve the equation for y, you need to isolate the term containing y on one side of the equation. Let's go through the steps to solve this equation:
1. Start with the original equation: 4y + 5x = -7.
2. To isolate the term with y, subtract 5x from both sides of the equation:
4y = -5x - 7.
3. Then divide both sides of the equation by 4 to solve for y:
y = (-5x - 7) / 4.
So, the correct solution is:
y = (-5x - 7) / 4.
In your solution, you made a small error. The constant term in the numerator should be -7, not +4. Hence, the correct solution is y = (-5x - 7) / 4.
