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 + 3c = c + 9y + 5 for c in terms of y.
| 1\(\frac{2}{7}\)y + \(\frac{2}{7}\) | |
| 6y + 5 | |
| \(\frac{7}{9}\)y + \(\frac{1}{3}\) | |
| 4y - 6 |
