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 - 6c = 6c + 5z - 2 for c in terms of z.
| -\(\frac{11}{13}\)z + \(\frac{2}{13}\) | |
| -6z + 7 | |
| -2z - 3 | |
| z - 7 |
