Solve for k: 4 + k − 2k = 16 + 3k

Question

Quizplus · Accepted Answer

4 + k − 2k = 16 + 3k
Step 1: Simplify. Combine like terms (k - 2k = -k). Remember that variables without a coefficient (number in front) actually have the coefficient of 1, we just don't write the 1. So, it is 1k - 2k = -1k.
4 + k − 2k = 16 + 3k
4 − k = 16 + 3k
Step 2: Subtract 4 from both sides of the equation.
4 − 4 − k = 16 − 4 + 3k
− k = 12 + 3k
Step 3: Isolate the variable on one side of the equation by subtracting 3k from both sides.
− k − 3k = 12 + 3k − 3k
−4k = 12
Step 4: Divide both sides of the equation by −4.
−4k ÷ −4 = 12 ÷ −4
