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