Question

Find a value of x that is a solution to 5(x – 3) = x + 13.

Answer 1

x=7

Explanation:

`5(x-3)=x+13\\5x-15=x+13\\Subtract x from both sides \\4x-15=13\\Add 15 to both sides\\4x= 28\\Divide both sides by 4\\x=7`

Now check your answer

`5(7-3)=7+13\\35-15=20\\20=20`

Answer 2

x = 7

Explanation:

`5(x-3)=x+13`

distribute

`5x-15= x+13`

combine like terms

`5x-x = 13 + 15`

`4x=28`

x = 7
