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 -2c + 5c = -7c - 4y + 7 for c in terms of y.
| \(\frac{1}{8}\)y - 1\(\frac{1}{8}\) | |
| \(\frac{1}{5}\)y + \(\frac{1}{10}\) | |
| -1\(\frac{4}{11}\)y + \(\frac{6}{11}\) | |
| -1\(\frac{4}{5}\)y + 1\(\frac{2}{5}\) |
