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