When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -4c - 7c = -8c + 6y - 5 for c in terms of y.
| -\(\frac{7}{15}\)y + \(\frac{4}{15}\) | |
| y - 1 | |
| 3\(\frac{1}{4}\)y - 1\(\frac{1}{4}\) | |
| -6y + 7 |
