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