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 2b - 8b = -b - 5y + 8 for b in terms of y.
| -\(\frac{6}{11}\)y + \(\frac{7}{11}\) | |
| \(\frac{3}{7}\)y + \(\frac{9}{14}\) | |
| y + 2\(\frac{2}{3}\) | |
| -\(\frac{15}{16}\)y + \(\frac{9}{16}\) |
