Here, we are to calculate for the value of x.
We start by finding the Lowest common multiples of both fractions. The lowest common multiple of both fractions is 14
Now, we can multiply each of the terms in the question by 14. Thus, we have;
14(x + 3)/2 + 14(2x/7) = (7 * 14)
7(x + 3) + 2(2x) = 98
Opening the brackets, we have;
7x + 21 + 4x = 98
Collect like terms;
7x + 4x = 98 - 21
11x = 77
x = 77/11
x = 7
