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 -8b - 3b = 8b - 2y + 7 for b in terms of y.
| -1\(\frac{1}{2}\)y - \(\frac{3}{4}\) | |
| \(\frac{1}{7}\)y - 1\(\frac{1}{7}\) | |
| -\(\frac{1}{16}\)y - \(\frac{7}{16}\) | |
| \(\frac{3}{8}\)y - \(\frac{1}{8}\) |
