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 -5c + 4c = -6c + 7z - 8 for c in terms of z.
| -1\(\frac{2}{5}\)z + \(\frac{3}{5}\) | |
| 10z - 9 | |
| 3z - 8 | |
| z + 2 |
