Answer:
y = -4
Step-by-step explanation:
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
2 + 2y = 2 • (y + 1)
Equation at the end of step 2 :
3y - 4 • (y + 1) = 0
Step 3 :
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
-y - 4 = -1 • (y + 4)
Equation at the end of step 4 :
-y - 4 = 0
Step 5 :
Solving a Single Variable Equation :
5.1 Solve : -y-4 = 0
Add 4 to both sides of the equation :
-y = 4
Multiply both sides of the equation by (-1) : y = -4
One solution was found :
y = -4
