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 10c - 2c = 9c + 8z + 8 for c in terms of z.
| 3z + 2 | |
| \(\frac{7}{11}\)z - \(\frac{9}{11}\) | |
| 10z + 8 | |
| 1\(\frac{3}{7}\)z + \(\frac{1}{7}\) |
