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