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