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 - 9c = -3c + 5z + 2 for c in terms of z.
| -14z - 2 | |
| \(\frac{5}{6}\)z + 1\(\frac{1}{3}\) | |
| \(\frac{8}{9}\)z + 1 | |
| \(\frac{5}{9}\)z + \(\frac{1}{9}\) |
