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 - 7c = -4c - 3z - 7 for c in terms of z.
| \(\frac{5}{6}\)z + \(\frac{1}{2}\) | |
| -z + 1\(\frac{3}{4}\) | |
| -\(\frac{2}{13}\)z - \(\frac{6}{13}\) | |
| -4z + 1 |
