Answer:
Do the distributive property; your new equation will be 9x + 18 = 90
Step-by-step explanation:
The first step to the problem 9(x + 2) = 90 is the distribute property. Since we don't know what x is we can't add it to 2. Instead we do the distributive property, which is when you multiply the outside number to the terms inside the parenthesis.
The equation will then be: 9x + 18 = 90
