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