Find the least common denominator (LCD) for the fractions in each list. 7\. \(\frac{4}{5}, \frac{1}{3}, \frac{3}{10}\)

By what number is it necessary to multiply both sides of each equation to isolate x on the left side? Do not actually solve. $$ \frac{x}{10}=5 $$

Solve each equation, and check the solution. \(4 x+3=27\)
