Parentheses are used to identify which numbers you should add,multiply .ect first. So If i had

12-(3+1)=x    

then you would want to solve 3+1 before you subtract 12.

How many solutions does the following equation have 3(X + 9) = 2x + 54
kotykmax [81]

Answer:

One solution.

Step-by-step explanation:

3(x + 9) = 2x + 54

3x + 27 = 2x + 54

3x + 27 - 2x = 2x + 54 - 2x

x + 27 = 54

x + 27 - 27 = 54 - 27

x = 27
