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 -4c + 7c = 7c + x + 7 for c in terms of x.
| \(\frac{6}{11}\)x - \(\frac{7}{11}\) | |
| -\(\frac{1}{2}\)x + 3\(\frac{1}{2}\) | |
| \(\frac{7}{15}\)x + \(\frac{4}{15}\) | |
| -2\(\frac{1}{5}\)x + \(\frac{1}{5}\) |
