Question

when 20 is added to 7 times the number x, the result is -1. What number results when 2 times x is subtracted from 5?

Answer 1

The number is 11

7x +20 =-1

7x = -21

x = -3

7(-3) +20=-1

-21 +20 = -1

Two times x = two times  -3 = -6

5 -(-6)= 11

5-(-6) =11

Answer 2

The answer is x=1 there you go
