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