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