Question

Solve the equation 56k - 30 + k = 100.

(a) k = 5
(b) k = 4
(c) k = 3
(d) k = 6

Answer 1

The equation is solved by combining like terms, rewriting the equation, and isolating k. However, the solution calculated does not match any of the multiple-choice options provided.

Step-by-step explanation:

Solution for the Equation

To solve the equation 56k - 30 + k = 100, you'll first want to combine like terms.

1. Combine k terms: 56k + k = 57k.
2. Rewrite the equation: 57k - 30 = 100.
3. Add 30 to both sides: 57k = 130.
4. Divide both sides by 57 to find k: k = 130 / 57.
5. Calculate the value of k: k ≈ 2.28.

owever, this solution does not match any of the options provided, which suggests there may have been an error in the problem or the answer choices given. If you're confident in your calculations and can't reconcile the mismatch, you might want to double-check with your instructor or the source of the problem.
