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