Question

Solve each of the following equations and check your results.
9x-4(x-4)= 3x


​

Answer 1

Answer:

x = -8

Step-by-step explanation:

(9x -  4 • (x - 4)) -  3x  = 0  

Pull out like factors :

  2x + 16  =   2 • (x + 8)  

Equation at the end of step  3  :

 2 • (x + 8)  = 0  

Equations which are never true :

4.1      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

Solve  :    x+8 = 0  

Subtract  8  from both sides of the equation :  

x = -8

Answer 2

Answer:

Step-by-step explanation:

Solution

9x-4(x-4)= 3x

9x- 4x- 16 =3x

2x= 16

Therefore, X=8

Remember one thing side change sine change.
