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 - 5c = -5c + z + 3 for c in terms of z.
| \(\frac{1}{2}\)z + \(\frac{1}{4}\) | |
| -11z + 4 | |
| z - 2\(\frac{1}{4}\) | |
| \(\frac{3}{8}\)z + 1 |
