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 -5c + 9c = -8c - 8x - 7 for c in terms of x.
| \(\frac{9}{10}\)x + \(\frac{1}{5}\) | |
| \(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| -5\(\frac{2}{3}\)x - 2\(\frac{1}{3}\) | |
| \(\frac{7}{15}\)x + \(\frac{3}{5}\) |
