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 - 7c = 2c + z + 7 for c in terms of z.
| -1\(\frac{5}{7}\)z - 1\(\frac{2}{7}\) | |
| 2z + 1\(\frac{3}{4}\) | |
| -1\(\frac{3}{11}\)z + \(\frac{7}{11}\) | |
| -1\(\frac{2}{7}\)z - 1 |
