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 -2a - 2a = a + 3y - 2 for a in terms of y.
| \(\frac{5}{7}\)y + \(\frac{2}{7}\) | |
| -1\(\frac{2}{3}\)y + \(\frac{2}{3}\) | |
| -1\(\frac{3}{8}\)y + 1 | |
| \(\frac{5}{11}\)y + \(\frac{1}{11}\) |
