A good way to solve this problem is by multiplying the terms with the LCD; or the Least Common Denominator.

Explanation:

(x+3)/2+(2x)/7=7

Multiply the terms with 14; the Least Common Denominator of the three terms within the equation.

7(x+3) +2(2x)=98

Now, just solve for x.

7x+21+4x=98

11x=77

x=7
