Solution Steps

To solve the equation x2+x7=9\frac{x}{2} + \frac{x}{7} = 9, we need to find a common denominator for the fractions on the left side. The common denominator of 2 and 7 is 14. Rewrite each fraction with this common denominator, combine them, and then solve for xx.

Step 1: Find a Common Denominator

To solve the equation x2+x7=9\frac{x}{2} + \frac{x}{7} = 9, we first find a common denominator for the fractions. The least common denominator of 2 and 7 is 14.

Step 2: Rewrite the Equation

Rewrite each fraction with the common denominator: 7x14+2x14=9 \frac{7x}{14} + \frac{2x}{14} = 9

Step 3: Combine the Fractions

Combine the fractions on the left side: 9x14=9 \frac{9x}{14} = 9

Step 4: Solve for xx

To solve for xx, multiply both sides by 14 to eliminate the fraction: 9x=126 9x = 126 Then, divide both sides by 9: x=1269=14 x = \frac{126}{9} = 14

Final Answer

x=14 \boxed{x = 14}
