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 + 6b = -8b + 8x + 7 for b in terms of x.
| \(\frac{4}{7}\)x + \(\frac{2}{7}\) | |
| \(\frac{1}{6}\)x + \(\frac{7}{12}\) | |
| -\(\frac{5}{7}\)x + \(\frac{1}{7}\) | |
| -\(\frac{8}{11}\)x + \(\frac{8}{11}\) |
