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 -8c + 7c = 2c - 6x + 7 for c in terms of x.
| \(\frac{1}{9}\)x + \(\frac{4}{9}\) | |
| \(\frac{7}{12}\)x + \(\frac{3}{4}\) | |
| 1\(\frac{3}{10}\)x - \(\frac{7}{10}\) | |
| x + 1\(\frac{3}{4}\) |
