You need to specify the statement needed to use the equation. Thank you. I will then answer it if needed.
Multiply both sides by the reciprocal (-8/7). You would get 40/7 or 5.71428571
The ordered pair (7, 19) is only a solution to the first equation, 14-19= -5. the ordered pair is not a solution to the second equation 7 + 57 does not equal 22.
Easy do 12 times 16 divided by two = 96
answer=96
