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 2b + 8b = b - 7y + 5 for b in terms of y.
| -\(\frac{4}{7}\)y - \(\frac{6}{7}\) | |
| -\(\frac{1}{4}\)y + 2 | |
| -15y + 5 | |
| 1\(\frac{3}{4}\)y + \(\frac{3}{4}\) |
