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