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 - 2c = -c - 2y - 6 for c in terms of y.
| y + 6 | |
| \(\frac{5}{16}\)y + \(\frac{1}{16}\) | |
| -4y - 3 | |
| \(\frac{6}{7}\)y + \(\frac{3}{7}\) |
