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 + 7b = 3b - 2y - 7 for b in terms of y.
| -2\(\frac{1}{8}\)y + 1 | |
| y - \(\frac{3}{8}\) | |
| y + \(\frac{7}{9}\) | |
| y + \(\frac{1}{5}\) |
