Question

Substitute x = 2 into each equation. Which two equations have the solution x = 2?

Answer 1

Explanation:

The two equations that have the solution x = 2 when x is substituted for 2 are:

Equation 1: 2 + 3x = 10

2 + 3(2) = 10

2 + 6 = 10

8 = 10

Equation 2: 2x + 4 = 10

2(2) + 4 = 10

4 + 4 = 10

8 = 10
