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