Answer: Beth is correct, there is only one solution.
Step-by-step explanation:
x + 3 = 5
Get x by itself by subtracting 3 from both sides of the equation.
x = 2
x is equal to two and no other number can be substituted in for x that will equal 5.
Check answer by putting 2 in for x.
2 + 3 = 5
Correct!
