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 -2c + 7c = -6c + 7x + 8 for c in terms of x.
| 2\(\frac{1}{4}\)x + 1\(\frac{1}{4}\) | |
| x + 2 | |
| -13x - 8 | |
| -3x + 4\(\frac{1}{2}\) |
