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 - 4c = 7c + 3x - 5 for c in terms of x.
| -\(\frac{7}{12}\)x + \(\frac{5}{12}\) | |
| x - 1\(\frac{2}{3}\) | |
| 2\(\frac{3}{4}\)x + 1\(\frac{3}{4}\) | |
| 1\(\frac{5}{9}\)x + 1 |
