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 - 8c = 9c + 2x + 2 for c in terms of x.
4x + 5 | |
x - \(\frac{3}{11}\) | |
-3x + 2 | |
-2x - \(\frac{2}{5}\) |
