Equations
Find the missing value of the variable:
x + 3 = 7
x = 4
Are 3x + 1 and 2x + 2 equivalent expressions? Explain your thinking.
They are not equivalent expressions because they will not always give the same result for every value of the variable.
Use the distributive property to simplify:
3(2 + 4)
6 + 12=
18
Evaluate 32.
