x=551

Explanation:

Before we add or subtract some terms, we need to make our fractions have a common denominator. We can multiply the numerator and denominator in 217 by 3 to get 651. Now, we have:

151+x=651

Now, we can subtract 151 from both sides to get:

x=551

NOTE: We can multiply the numerator and denominator both by 3 because this is essentially multiplying the fraction by 1. It does not change the meaning of the expression.
