Integrating both sides once gives

where
is an arbitrary constant vector. Use the initial condition to find its value:


Integrate again:

where
is another arbitrary vector of constants. Use the other initial condition to determine its components:


Then the particular solution to this ODE is

7/10x + 14 < 49
Hope this helps.
3^4 = 3 x 3 x 3 x 3
4^3 = 4 x 4 x 4
3^3 = 3 x 3 x 3 = 27
Hope it helps!
