By definition of absolute value, if x-1\ge0, then |x-1|=x-1, so

|x-1|=5x+2\implies x-1=5x+2\implies4x=-3\implies x=-\dfrac34

On the other hand, if x-1, then |x-1|=-(x-1)=1-x, and

|x-1|=5x+2\implies1-x=5x+2\implies6x=-1\implies x=-\dfrac16

dmitriy555 [2]
X = number of singles matches
y = number of doubles mnathes

so we have the equation x + y = 13.......(1)

also 

2x + 4y  = 38 ...........(2)

(1) and (2) are the required equations

b)  Find how many maches are in progress by solivng the above equations:-

x + y  =  13   multiply this by -2:-
-2x - 2y = -26
2x + 4y = 38   Adding to removes the  terms in x:-

2y = 12

y = 6  

so x = 13-6 = 7

So the answer is  6 double matches and 7 singles are in progress.
