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 + 2b = 7b - 7y - 4 for b in terms of y.
| -\(\frac{3}{11}\)y + \(\frac{5}{11}\) | |
| y + \(\frac{4}{9}\) | |
| -\(\frac{1}{3}\)y - 2 | |
| \(\frac{3}{7}\)y - 1\(\frac{2}{7}\) |
