Multiply me by 7. then subtract 17.if you subtract 10 and then add 5 you get 20. what number am i ?
ANEK [815]

Hello from MrBillDoesMath!

Answer:

6

Discussion:

Let the unknown number called "x". Then the question states that

(7x -17) - 10 + 5 = 20                     =>

7x  + (-17 - 10 + 5) = 20                  => as -17 -10 + 5  =-27 +5 = -22

7x -22 = 20                                   => add 22 to both sides

7x = 20 + 22                                 => 20 + 22 = 42

7x = 42                                          => divide both sides by 7

x = 42/7 = 6

Thank you,

MrB
