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 10a + 6a = 9a + 4y + 3 for a in terms of y.
| -\(\frac{1}{4}\)y + \(\frac{1}{8}\) | |
| -\(\frac{1}{3}\)y + \(\frac{1}{3}\) | |
| -2y + 3 | |
| 1\(\frac{6}{7}\)y - 1\(\frac{1}{7}\) |
