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 4c - 7c = 2c + z - 4 for c in terms of z.
| 3\(\frac{3}{4}\)z + 1 | |
| z + 7 | |
| 4z - 2 | |
| -\(\frac{5}{17}\)z + \(\frac{8}{17}\) |
