Answer:

NO

Step-by-step explanation:

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

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

g = 12 ← is the only solution

Answer:

No.

Step-by-step explanation:

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

Substitute 15 in for g:

[tex]19-15=7[/tex]

Solve:

[tex]4\neq 7[/tex]

15 isn't a solution to the equation.

The only solution valid is when g = 12.

Substitute 12 in for g:

[tex]19-12=7[/tex]

Solve:

[tex]7=7[/tex]
