Question

solve for j.
2(j - 12.3) - 7.6 = 4.8
j = \boxed{}

Explanation:

Step1: Isolate the parenthetical term

Add 7.6 to both sides.
$$2(j - 12.3) = 4.8 + 7.6$$
$$2(j - 12.3) = 12.4$$

Step2: Solve for the parenthetical

Divide both sides by 2.
$$j - 12.3 = \frac{12.4}{2}$$
$$j - 12.3 = 6.2$$

Step3: Solve for $j$

Add 12.3 to both sides.
$$j = 6.2 + 12.3$$

Answer:

18.5
