how do I write 3x-2y=7 to get y by itself? thank u
would it be: y = 3.5 + -1.5x
??
thanks again
You have the right idea, but watch your sign:
3x-2y=7
Subtract 3x from both sides:
-2y = -3x + 7
Divide by -2
y = (3/2)x -7/2
To get y by itself in the equation 3x - 2y = 7, you can follow these steps:
Step 1: Start with the equation 3x - 2y = 7.
Step 2: Subtract 3x from both sides of the equation to isolate the -2y term.
3x - 2y - 3x = 7 - 3x
Simplifying, we get:
-2y = 7 - 3x
Step 3: Divide both sides of the equation by -2 to solve for y.
(-2y) / (-2) = (7 - 3x) / (-2)
Simplifying, we get:
y = (-7 + 3x) / 2
Therefore, to get y by itself, the equation can be expressed as y = (-7 + 3x) / 2.
