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 5c - 6c = 7c + 7z + 2 for c in terms of z.
| -2\(\frac{1}{4}\)z + \(\frac{1}{2}\) | |
| -\(\frac{11}{16}\)z + \(\frac{7}{16}\) | |
| z + 1 | |
| -6\(\frac{1}{2}\)z - 1 |
