D) 2X+3X+9=8(6-X) E)4(X+10)-2(X-5)=0 F)3(2X+3)-4(X-1)=3 G)7(X-1)-2(X-5)=X-5
H)2(3-X)=3(X-4)+15 SE ALGUEM RESPOMDER PFR POE A CONTA OBG..

Answer 1

a) 7x-28=12-4x
7x+4x=12+28
11x=40
x= 40/11
x= 3.6363636364
-----------------------'---
b) 10x-5= -2x - 6
10x+2x= -6+5
12x= -1
x= 12/-1
x= -12
-------------------'-----
c) -3x-6+5x-3=16
2x=16-5+6
2x=17
x= 17/2
x= 8,5
