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 - 6b = b - y - 7 for b in terms of y.
| -\(\frac{8}{9}\)y - \(\frac{4}{9}\) | |
| -1\(\frac{2}{3}\)y + 2\(\frac{1}{3}\) | |
| -\(\frac{5}{7}\)y - 1\(\frac{2}{7}\) | |
| \(\frac{1}{8}\)y + \(\frac{5}{8}\) |
