-3x+7 x=-2<br> PLEASE SHOW WORK. Thanks
galben [10]

Answer:

1  :

Step  2  :

Equations which are never true :

2.1      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    2x+1 = 0

Subtract  1  from both sides of the equation :

                     2x = -1

Divide both sides of the equation by 2:

                    x = -1/2 = -0.500

One solution was found :

                  x = -1/2 = -0.500
