How do i change these into y=?

3x – 2y = –1 --> -2y= -1-3x
5x + 2y = 25 --> 2y= 25-5x

first equation. multiply both sides by -1/2

second equation: multlipy both sides by 1/2

the original equation?

Do you mean...
-1/2(-2y)=-1/2(-1-3x)?

yes, giving y=1/2 + 3/2 x

oh alright thanks(:

To change the given equations into the form y = ?, you need to isolate the variable y on one side of the equation. Let's go through the process step by step for each equation:

1. 3x - 2y = -1
Start by moving the 3x term to the right side of the equation.
Subtract 3x from both sides:
-2y = -1 - 3x

Now, to isolate y, divide the entire equation by -2 (the coefficient of y):
-2y / -2 = (-1 - 3x) / -2
This simplifies to:
y = (3x + 1) / 2

Therefore, y = (3x + 1) / 2 is the equation in the y = ? form.

2. 5x + 2y = 25
Start by moving the 5x term to the left side of the equation.
Subtract 5x from both sides:
2y = 25 - 5x

Now, to isolate y, divide the entire equation by 2 (the coefficient of y):
2y / 2 = (25 - 5x) / 2
This simplifies to:
y = (25 - 5x) / 2

Therefore, y = (25 - 5x) / 2 is the equation in the y = ? form.
