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