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 -9c - 4c = -7c + z + 4 for c in terms of z.
| \(\frac{5}{9}\)z + \(\frac{4}{9}\) | |
| -2\(\frac{2}{3}\)z + 1 | |
| -2\(\frac{1}{2}\)z - 2 | |
| -12z + 8 |
