solve for j.\n3j = 9(j - 10)\nj =

Explanation:

Step1: Expand the right - hand side

$$3j=9j - 90$$

Step2: Move the terms with (j) to one side

Subtract (9j) from both sides: $$3j-9j=9j - 90-9j$$ $$-6j=-90$$

Step3: Solve for (j)

Divide both sides by (-6): $$j=\frac{-90}{-6}$$ $$j = 15$$

Answer:

(15)
