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 + 7b = -8b - 8y + 5 for b in terms of y.
| -\(\frac{1}{6}\)y - 1\(\frac{1}{6}\) | |
| -11y + 1 | |
| -2\(\frac{1}{2}\)y + \(\frac{5}{6}\) | |
| -\(\frac{5}{6}\)y + 1\(\frac{1}{2}\) |
