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 -8b - 7b = 2b - 8y - 9 for b in terms of y.
| -2\(\frac{1}{4}\)y - 2\(\frac{1}{4}\) | |
| \(\frac{1}{10}\)y + \(\frac{9}{10}\) | |
| y + 1\(\frac{1}{2}\) | |
| -4\(\frac{1}{3}\)y + 2\(\frac{1}{3}\) |
