x%2F5%2Bx%2F7 Start with the given expression


Take note that the LCD is 35.


%287x%29%2F35%2Bx%2F7 Multiply the first fraction by 7%2F7


%287x%29%2F35%2B%285x%29%2F35 Multiply the second fraction by 7%2F7


%287x%2B5x%29%2F35 Combine the fractions (this is now possible since the denominators are equal)


%2812x%29%2F35 Add


So x%2F5%2Bx%2F7=%2812x%29%2F35
