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