First, we can convert feet to inches 1 foot=12 inches 7 feet=84 inches Next, we find out inches per hour 84 inches/27 1/2 hours ----------- -------------- 27 1/2 27 1/2 =3.054 inches/hour
X-20 = Y+20........ X-Y = 20+20........
X-Y = 40
AND
2Y-44=X+22............. Y-X= 44+22
Y-X=66
NOW, LET'S FIND X AND Y FROM THESE TWO EQUATIONS....
X-Y =40
Y-X= 66
IF WE COLLECT ....... 2Y = 106 AND Y = 53
THEN, USE Y IN ANY EQUATIONS FOR FINDING X
X-53 = 40 ..... X= 53+40 .......... X= 93
X= 93
Y=53
|x| < 7
means x < 7 and x > -7
answer is -7 < x < 7
