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 + 8c = 9c - 2y - 5 for c in terms of y.
| \(\frac{5}{8}\)y + \(\frac{5}{16}\) | |
| -1\(\frac{2}{3}\)y - 2 | |
| -\(\frac{3}{4}\)y - \(\frac{3}{4}\) | |
| -3\(\frac{1}{3}\)y + 1 |
