solve for j.\n7j + 1 = 4(-2j - 5) + 12j\nj =

Explanation:

Step1: Expand the right - hand side

$7j + 1=4\times(-2j)-4\times5 + 12j$ $7j + 1=-8j-20 + 12j$

Step2: Combine like terms on the right - hand side

$7j + 1=(-8j + 12j)-20$ $7j + 1 = 4j-20$

Step3: Move terms with $j$ to one side

$7j-4j=-20 - 1$

Step4: Combine like terms

$3j=-21$

Step5: Solve for $j$

$j=\frac{-21}{3}$

Answer:

$-7$
