    f(a) + g(a + 1) =

    7a + 2 + 8(a + 1) - 3 =

    7a + 2 + 8a + 8 - 3 =

    15a + 7

    f(x) = 7x+2, g(x) = 8x-3.;

    f(a) = 7a+2;

    g(a+1) = 8(a+1)-3 = 8a+5;

    f(a) + g(a+1) = (7a+2) + (8a+5) = (15a+7).

    If f(x) = 7x + 2 and g(x) = 8x - 3 

    f(a) + g(a + 1) 

    = 7a + 2 + 8(a + 1) - 3 

    = 15a + 7
