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 -9c + c = 6c + 2x + 1 for c in terms of x.
| -\(\frac{1}{15}\)x - \(\frac{1}{15}\) | |
| \(\frac{14}{15}\)x + \(\frac{1}{15}\) | |
| -x + 1\(\frac{1}{6}\) | |
| -1\(\frac{6}{7}\)x + \(\frac{6}{7}\) |
