Question 3 of 5
Two Variables

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 + 8b = -b + 7x - 5 for b in terms of x.

\(\frac{3}{5}\)x - \(\frac{4}{5}\)
-\(\frac{2}{7}\)x + \(\frac{3}{7}\)
-\(\frac{1}{4}\)x - 1\(\frac{1}{4}\)
\(\frac{3}{11}\)x + \(\frac{3}{11}\)
