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 7c - 3c = 8c + 4x + 2 for c in terms of x.
| -7x - 2 | |
| -\(\frac{3}{10}\)x + \(\frac{9}{10}\) | |
| -\(\frac{1}{8}\)x - 1\(\frac{1}{8}\) | |
| -12x + 5 |
