: I do not understand the how to solve these equations. I have to find the value of x in all of the problems. Problem 17 is using fractions in case you were wondering.
14. 2x-3(x+6)= -4(x-1)
15.2-3(x+4)= 9-(3+2x)
16.2.75-7.75(5-2x)= 26
17.1/2x+4= 2/3x This question is from textbook Prentice hall: Connected Mathematics2: Grade Eight

14. 2x-3(x+6)= -4(x-1)
2x-3x-18=-4x+4
2x-3x+4x=4+18
3x=22
x=22/3 ans.
----------------------------
15.2-3(x+4)= 9-(3+2x)
2-3x-12=9-3-2x
-3x+2x=9-3-2+12
-x=16
x=-16 ans.
-----------------------------
16.2.75-7.75(5-2x)= 26
2.75-38.75+15.5x=26
15.5x=26-2.75+38.75
15.5x=62
x=62/15.5
x=4 ans.
-----------------------
17.1/2x+4= 2/3x
x/2+4=2x/3
x/2-2x/3=-4
(3x-2*2x)/)2*3)=-4
(3x-4x)/6=-4
-x=-24
x=-24/-1
x=24 ans.
