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 - 9z + 5 for c in terms of z.
| 1\(\frac{4}{7}\)z - \(\frac{5}{7}\) | |
| -6z + 2\(\frac{1}{2}\) | |
| 2\(\frac{5}{6}\)z + 1 | |
| -2z - 9 |
