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