y + 1 = 2y + 5
Subtracting y on both sides
1 = y + 5
subtracting 1 on both sides
0 = y + 4
Therefore y = -4

y + 1 = 2y + 5
- y - y
1 = y + 5
- 5 - 5
- 4 = y
Therefore y = - 4

y + 1 = 2y + 5
subtract 5 from each side y + 1 - 5 = 2y + 5 - 5
y - 4 = 2y
subtract y from each side y - y - 4 = 2y - y
-4 = y

y+1 = 2y+5
subtract y from both sides
1 = y + 5
subtract 5 from both sides (isolate y)
-4 = y
Check:
-4+1 = 2(-4) + 5
-3 = -8 + 5
-3 = -3 works

y+1 = 2y+5
=> 2y-y = 1 - 5 (move around the variables)
=> y = -4 (answer)

y+1=2y+5
-y -y
1=y+5
-5 -5
y=-4
check your answer
(-4) + 1= -3
2(-4)+5=-3
YOU DID IT!

first you need to subtract y from both sides so that you get
1 = y + 5 then you can subtract 5 from both sides so that you get
-4 = y so then y = -4
