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