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 - 2c = -3c - 2y + 8 for c in terms of y.
| -1\(\frac{3}{5}\)y - 1\(\frac{4}{5}\) | |
| -\(\frac{5}{11}\)y - \(\frac{3}{11}\) | |
| y - 8 | |
| 1\(\frac{3}{7}\)y - \(\frac{5}{7}\) |
