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 -8c - 4c = -6c + 3z + 7 for c in terms of z.
| 5z + 2\(\frac{1}{3}\) | |
| -3\(\frac{1}{2}\)z - 3\(\frac{1}{2}\) | |
| -2\(\frac{1}{2}\)z + 3 | |
| -1\(\frac{1}{10}\)z + \(\frac{1}{10}\) |
