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 + 3c = -7c + 7x + 5 for c in terms of x.
| -1\(\frac{3}{8}\)x + \(\frac{1}{4}\) | |
| \(\frac{1}{6}\)x + \(\frac{1}{3}\) | |
| 2x - \(\frac{1}{7}\) | |
| \(\frac{1}{2}\)x + \(\frac{5}{8}\) |
