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 -5b - 3b = 3b + 8y - 9 for b in terms of y.
| -\(\frac{3}{11}\)y + \(\frac{8}{11}\) | |
| -1\(\frac{3}{8}\)y + 1\(\frac{1}{8}\) | |
| -y + 5 | |
| 1\(\frac{1}{7}\)y + \(\frac{5}{7}\) |
