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