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