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 + 3c = -6c - 2y + 1 for c in terms of y.
| -\(\frac{2}{9}\)y - \(\frac{5}{9}\) | |
| 2\(\frac{2}{7}\)y - \(\frac{4}{7}\) | |
| -\(\frac{5}{13}\)y + \(\frac{1}{13}\) | |
| \(\frac{5}{7}\)y - 1\(\frac{2}{7}\) |
