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