Answer:  x=3/2  
Step-by-step explanation:
Multiply the parentheses by 2/3.  9=2/3x+8.
Multiply  both sides by 3 .  27=2x+24
Move the term. When moved to the left side it changes from positive to a negative.  -2x=24-27.
-2x=-3 
Divide both sides by -2
x=3/2   (x=1 1/2, x=1.5)

<u>Given </u><u>:</u><u>-</u>
- The slope of the line through points (3,y) and (4,10) is 7 .
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
<u>Solution</u><u> </u><u>:</u><u>-</u>
As we know that the slope of the line is difference of ordinate divided by the difference of absicca as ,
 m = y -10 / 3 - 4
 m = y -10 / 3 - 4
 7 (-1) = y -10
 7 (-1) = y -10 
 -7 = y -10
 -7 = y -10
 y = 10 -7
 y = 10 -7
 y = 3
 y = 3
<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>3.</u>
