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