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 c - 2c = 5c + 3x - 7 for c in terms of x.
| \(\frac{1}{3}\)x + \(\frac{2}{3}\) | |
| -1\(\frac{1}{4}\)x + 1\(\frac{3}{4}\) | |
| 17x - 5 | |
| \(\frac{2}{5}\)x + \(\frac{2}{5}\) |
