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 = 0This 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
