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 + 7c = -3c - 3z - 7 for c in terms of z.
| -\(\frac{1}{4}\)z + \(\frac{1}{3}\) | |
| 1\(\frac{5}{6}\)z + \(\frac{5}{6}\) | |
| 10z + 7 | |
| z - 1\(\frac{2}{3}\) |
