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 3c - 7c = -9c - 6z + 3 for c in terms of z.
| \(\frac{1}{5}\)z + \(\frac{1}{2}\) | |
| z - \(\frac{2}{5}\) | |
| \(\frac{1}{12}\)z + \(\frac{1}{4}\) | |
| -1\(\frac{3}{7}\)z - 1\(\frac{1}{7}\) |
