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 7c + 7c = 6c + 5z - 2 for c in terms of z.
| -\(\frac{2}{7}\)z + \(\frac{4}{7}\) | |
| \(\frac{1}{8}\)z - \(\frac{9}{16}\) | |
| -1\(\frac{3}{4}\)z + 2 | |
| -2z - 2 |
