Question

The sum of -7 times a number and 8 times the sum of the number and 1 is the same as the number minus 7

Answer 1

False

Explanation:

-7x+8(x+1)=x-7

x+8=x-7

8=-7??

This is a false statement. 8 cannot equal -7

Answer 2

8 = -7

This statement is false.

Explanation:

The number will be represented by x

-7x + 8(x + 1) = x - 7

8 * x = 8x

8 * 1 = 8

-7x + 8x + 8 = x - 7

Add like terms

-7x + 8x = x

x + 8 = x - 7

-x -x

8 = -7

This statement is false.
