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 -8b - 5b = -4b + 2y + 1 for b in terms of y.
| 13y - 2 | |
| -1\(\frac{3}{4}\)y - \(\frac{1}{4}\) | |
| -y - 1 | |
| 1\(\frac{4}{7}\)y + 1\(\frac{2}{7}\) |
