Answer: x = 1/2

Explanation:

Rearrange:

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

4*(2*x-3)-3*(x-4)+7*x-(6)=0

Step by step solution :

STEP

1

:

Equation at the end of step

1

:

(((4•(2x-3))-3•(x-4))+7x)-6 = 0

STEP

2

:

Equation at the end of step

2

:

((4•(2x-3)-3•(x-4))+7x)-6 = 0

STEP

3

:

STEP

4

:

Pulling out like terms :

4.1 Pull out like factors :

12x - 6 = 6 • (2x - 1)

Equation at the end of step

4

:

6 • (2x - 1) = 0

STEP

5

:

Equations which are never true :

5.1 Solve : 6 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.2 Solve : 2x-1 = 0

Add 1 to both sides of the equation :

2x = 1

Divide both sides of the equation by 2:

x = 1/2

One solution was found :

x = 1/2
