-2y = 4 - y - 3
y - 2y = 4 - 3
y * (1 - 2) = 4-3
y = (4-3) / (1-2)
y = 1/-1
y = -1

3 - 2y = 4 - y
3 = 4 + y Add 2y to both sides
-1 = y Subtract 4 from both sides
y = -1
Check:
3 - 2(-1) = 4 - (-1)
3 + 2 = 4 + 1
5 = 5 Check!

3 - 2y = 4 - y
3 - 2y + y = 4 = y + y
3 - y = 4
3 - y - 3 = 4 - 3
- y = 1
-1(- y) = - 1(1)
y = - 1
The aswer is y = - 1
Inseert the y value into the equation
- - - - - - - - - - - - - - - - - - - - - - - -
Check
3 - 2y = 4 - y
3 - 2(- 1) = 4 - ( - 1)
3 - (- 2) = 4 + 1
3 + 2 = 5
5 = 5

3-2y= 4-y
Collect all like terms together
3-2y-4+y=0
3-2y+y-4=0
3-y-4=0
-1-y=0
-1=y
y=-1
Btw why do we have to do your homework little junior?

3-2y=4-y
take all y values onto same side
-2y+y=4-3
-y=1
y=-1
