Answer:


\huge\boxed{j=38}

Explanation:


(j)/(-2)+7=-12\qquad\text{subtract 7 from both sides}\\\\(j)/(-2)+7-7=-12-7\\\\(j)/(-2)=-19\qquad\text{multiply both sides by (-2)}\\\\(-2)\!\!\!\!\!\!\!\diagup\cdot(j)/(-2\!\!\!\!\!\diagup)=(-2)(-19)\\\\j=38

Answer: j = 38

Step-by-step explanation: First isolate j/-2 by subtracting

7 from both sides of the equation.

That gives you j/-2 = -19.

From here, since j is being divided by -2, multiply

both sides of the equation by -2 so j = 38.
