Question

If five times a number plus two is 17 what is the number

Answer 1

5 times a number plus two is 17

5(x) + 2 = 17

isolate the x, do the opposite of PEMDAS 

(Note: What you do to one side you do to the other, because of equal sign)

5x + 2 (-2) = 17 (-2)

5x = 15

5x/5 = 15/5

x = 3


hope this helps
