The answer is 14 you just have to substitute x with the given number and finish the equation
A(b-c)=ab-ac
(1/7)(1/3h-1/2)=(1/7)(1/3h)-(1/7)(1/2)=1/21h-1/14
now we gots
6 and 1/7+1/21h-1/14
rearange
6 and 1/7-1/14+1/21h
make common denom which is 14
6 and 2/14-1/14+1/21h
6 and 1/14+1/21h
The given equations are

TO solve for p and w, we can use elimination method. And the first step is to eliminate p by adding both equations .
So out of the given options, correct option is the first option .
The answer are:
(-4,5)
(2,2)
(-1, -3)
(3,4)
(2,-1)
(-5,6)
