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