Question

How do you solve equations through substitution and using inverse operations?

Answer 1

Answer:

n = 45

Step-by-step explanation:

Rearrange:

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

2+2*(4+3)+4+4*n-(200)=0

Step  1  :

Pulling out like terms :

  -180 + 4n  =   4 • (n - 45)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    n-45 = 0

Add  45  to both sides of the equation :

                     n = 45

One solution was found :

                  n = 45
