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 + 5c = -9c + 4z - 2 for c in terms of z.
| \(\frac{3}{7}\)z + \(\frac{5}{7}\) | |
| -\(\frac{1}{14}\)z - \(\frac{1}{7}\) | |
| -6z + 8 | |
| -6\(\frac{1}{2}\)z + 2\(\frac{1}{2}\) |
