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 + 3a = 6a - 2y + 1 for a in terms of y.
| 5y + 3 | |
| \(\frac{2}{3}\)y + 1\(\frac{1}{3}\) | |
| \(\frac{5}{9}\)y - \(\frac{1}{9}\) | |
| \(\frac{1}{8}\)y - \(\frac{3}{8}\) |
