Answer:
j = 2/19
Step-by-step explanation:
Step 1: Subtract 7 on both sides
-2/j = -19
Step 2: Multiply <em>j</em> on both sides
-2 = -19j
Step 3: Divide both sides by -19
2/19 = j
If the question is -2/(j + 7) = 12:
Step 1: Multiply both sides by j + 7
-2 = 12(j + 7)
Step 2: Distribute
-2 = 12j + 84
Step 3: Subtract 84 on both sides
-86 = 12j
Step 4: Divide 12 on both sides
j = -43/6 = -7.167
