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 - 3c = 8c + 4x - 7 for c in terms of x.
| \(\frac{5}{13}\)x + \(\frac{9}{13}\) | |
| -2\(\frac{1}{3}\)x + 2\(\frac{1}{3}\) | |
| \(\frac{5}{9}\)x + \(\frac{2}{3}\) | |
| \(\frac{3}{4}\)x + \(\frac{1}{2}\) |
