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 + 7c = -2c - 9x + 5 for c in terms of x.
| -1\(\frac{7}{9}\)x + \(\frac{5}{9}\) | |
| -\(\frac{4}{9}\)x + \(\frac{8}{9}\) | |
| -2\(\frac{1}{3}\)x + 3 | |
| 1\(\frac{1}{11}\)x - \(\frac{7}{11}\) |
