Answer:
[tex]\huge\boxed{j=38}[/tex]
Step-by-step explanation:
[tex]\dfrac{j}{-2}+7=-12\qquad\text{subtract 7 from both sides}\\\\\dfrac{j}{-2}+7-7=-12-7\\\\\dfrac{j}{-2}=-19\qquad\text{multiply both sides by (-2)}\\\\(-2)\!\!\!\!\!\!\!\diagup\cdot\dfrac{j}{-2\!\!\!\!\!\diagup}=(-2)(-19)\\\\j=38[/tex]
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.
