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 -9b + 4b = 6b + 4y + 8 for b in terms of y.
| \(\frac{5}{7}\)y - 1 | |
| -6y + 8 | |
| -\(\frac{1}{2}\)y + \(\frac{3}{7}\) | |
| y - \(\frac{8}{15}\) |
