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 -3b + 4b = 2b - 7y + 8 for b in terms of y.
| -1\(\frac{1}{3}\)y - 1 | |
| -\(\frac{1}{2}\)y + 4\(\frac{1}{2}\) | |
| -\(\frac{5}{7}\)y + \(\frac{5}{7}\) | |
| 2\(\frac{1}{5}\)y - 1\(\frac{3}{5}\) |
