Question

Solve for x: 5(x + 3) = 4(x − 3)

Answer 1

Answer:

x = -27

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 (5 • (x + 3)) -  4 • (x - 3)  = 0

Step  2  :

Equation at the end of step  2  :

 5 • (x + 3) -  4 • (x - 3)  = 0

Step  3  :

Equation at the end of step  3  :

 x + 27  = 0

Step  4  :

Solving a Single Variable Equation :

4.1      Solve  :    x+27 = 0

Subtract  27  from both sides of the equation :

                     x = -27

One solution was found :

                  x = -27
