Hello! The answer to your question would be as followed:

Rearrange:

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

-79-(7*w+3*(4*w-1)=0

-79 - (7w + 3 • (4w - 1)) = 0

Pulling out like terms :

Pull out like factors :

-19w - 76 = -19 • (w + 4)

-19 • (w + 4) = 0

Equations which are never true :

Solve : -19 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

Solve : w+4 = 0

Subtract 4 from both sides of the equation :

w = -4

w = -4
