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 + 6c = 9c + 6y - 3 for c in terms of y.
| -1\(\frac{7}{10}\)y + \(\frac{3}{5}\) | |
| y + 1\(\frac{1}{2}\) | |
| -y + 9 | |
| -\(\frac{2}{7}\)y + \(\frac{3}{7}\) |
