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 + 2b = 5b - 9y + 3 for b in terms of y.
| 3y - 3 | |
| \(\frac{2}{3}\)y + \(\frac{3}{5}\) | |
| \(\frac{11}{12}\)y - \(\frac{1}{4}\) | |
| -1\(\frac{8}{9}\)y - \(\frac{7}{9}\) |
