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