Finding the Solution to an Equation

In this video, we will be learning how to find the solution to an equation using direct substitution.

For example:

For what value of x would make this equation true?

$3x +1 = 7$       Begin by substituting an answer choice for x

A. 2                                           $3x +1 = 7$

B. 3                                           $3(2) +1 = 7$

C. 4                                           $6 +1 = 7$

D. 5                                           $7 = 7$
