Question

Solve for j : j/-2+7=-12 j=?

Answer 1

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.

Answer 2

Answer:

$\huge\boxed{j=38}$

Step-by-step explanation:

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