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 + 8b = 4b + 8y - 7 for b in terms of y.
| y + 7 | |
| -11y - 8 | |
| -2\(\frac{1}{4}\)y - 2 | |
| \(\frac{3}{10}\)y + \(\frac{9}{10}\) |
