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 -7c - c = -6c - 8y + 1 for c in terms of y.
| 7y - 1 | |
| y + 4 | |
| -1\(\frac{1}{9}\)y + \(\frac{1}{3}\) | |
| \(\frac{11}{16}\)y + \(\frac{5}{16}\) |
