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 -7b + 4b = -3b + 4y + 8 for b in terms of y.
| y - 2 | |
| \(\frac{3}{5}\)y + \(\frac{8}{15}\) | |
| \(\frac{14}{17}\)y + \(\frac{5}{17}\) | |
| \(\frac{7}{13}\)y - \(\frac{8}{13}\) |
