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