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 4c - c = 9c - 7x - 5 for c in terms of x.
| 10x + 6 | |
| 3x + 2 | |
| -\(\frac{1}{5}\)x + 1 | |
| 1\(\frac{1}{5}\)x + 1 |
