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 6a + 5a = 3a + 6y + 4 for a in terms of y.
| -2y - 1\(\frac{2}{3}\) | |
| \(\frac{1}{3}\)y + 1\(\frac{1}{3}\) | |
| y + \(\frac{3}{13}\) | |
| -1\(\frac{1}{10}\)y + \(\frac{7}{10}\) |
