3x+7=y-5
Wat do you need to do with that equation?
You need to find out what's x and what's y.
well, I would add 5 to both sides
3 x + 12 = y
or if you want x, subtract 7 from both sides first
3 x = y - 12
then divide all terms on both sides by 3
x = (y/3) - 4
The equation you provided is 3x + 7 = y - 5. To solve this equation, we can isolate the variable y by moving the terms that contain y to one side of the equation and moving the terms without y to the other side.
To do this, let's start by moving the term -5 from the right side to the left side of the equation. We can do this by adding 5 to both sides of the equation:
3x + 7 + 5 = y - 5 + 5
Simplifying the equation gives:
3x + 12 = y
So, the equation 3x + 7 = y - 5 is equivalent to 3x + 12 = y.
Therefore, y = 3x + 12.
