Answer:

No.

Explanation:

To tell whether g = 15 is a solution, you substitute (replace) 15 in the equation.

Substitute 15 in for g:


19-15=7

Solve:


4\\eq 7

15 isn't a solution to the equation.

The only solution valid is when g = 12.

Substitute 12 in for g:


19-12=7

Solve:


7=7

Answer:

NO

Explanation:

19 - g = 7 ( subtract 19 from both sides )

- g = - 12 ( multiply both sides by - 1 )

g = 12 ← is the only solution
