Question

How do I do this? 5(x+9)=5x+45

Answer 1

Answer:

x = 9; This problem is also true because 5x + 45 is equal to 5x + 45

Step-by-step explanation:

First you would distribute 5 into x and 9

5x + 45 = 5x + 45

Then we would divide both 45 on both sides by 5

5x + 45 = 5x + 45

        ÷5            ÷5

x = 9

Answer 2

5(x + 9) = 5x + 45      Multiply 5 into (x + 9)

5x + 45 = 5x + 45           This has unlimited amounts of solution because they are the same on both sides

5x + 45 = 5x + 45    Subtract 45 on both sides

5x = 5x     Subtract 5x on both sides

0 = 0
