Question

7y - 3y - 14 = 14

y =

Answer 1

Rearrange :

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

7*y-3*y-14-(14)=0
Step by step solution :
Step 1 :


Pulling out like terms :

1.1 Pull out like factors :

4y - 28 = 4 • (y - 7)
Equation at the end of step 1 :

4 • (y - 7) = 0

Step 2 :

Solve 4•(y-7) = 0

Equations which are never true :

2.1 Solve : 4 = 0

This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :

2.2 Solve : y-7 = 0

Add 7 to both sides of the equation :
y = 7
One solution was found :
y = 7
