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 -3c - 2c = -4c - 5z - 9 for c in terms of z.
| -3z + 5 | |
| -3z - 9 | |
| \(\frac{5}{11}\)z + \(\frac{5}{11}\) | |
| -\(\frac{1}{15}\)z + \(\frac{7}{15}\) |
