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