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 - 2c = 4c - 6z + 7 for c in terms of z.
| -1\(\frac{3}{8}\)z - \(\frac{3}{4}\) | |
| -\(\frac{1}{2}\)z - \(\frac{2}{5}\) | |
| \(\frac{1}{3}\)z - \(\frac{7}{12}\) | |
| -13z + 6 |
