Answer 1

3X+8= 24
3X=24-8
3X=16
X= $\frac{16}{3}$

9X-3=21
9X=21+3
9X=24 (SACAMOS TERCIA)
3X=8
X= $\frac{8}{3}$

- 1/2x+3/4=1/8
$\frac{-2X+3}{4}$ = $\frac{1}{8}$
-4X+6= 1
-4X=1-6
-4X=-5
X= $\frac{5}{4}$

2(X+1)-(X-1)=0
2X+2-X+1=0
X+3=0
X= -3

2(X-1)=2X+3
2X-2=2X+3
2X-2X=3+2
0X=5 NO EXISTE

-7(X+3)+6(2X+9)=6(X+3)
-7X-21+12X+54=6X+18
5X+33=6X+18
33-18=6X-X
15=5X
X=15/5
X= 3

4(3X+9)-2(5X+7)+7(X+3)= -2(X+1)+2(X-7)
12X+36-10X-14+7X+21=-2X-2+2X-14
9X+43=-16
9X= - 16 - 43
9X= - 59
X= -59/9

X/2+X/3=X/5+8
15X+10X=240+6X
25X-6X=240
19X=240
X=240/19

4/9(X+3/2)+3/2(X-1/2)-3/2X=9/4
$\frac{16X+24+54X-27-54X}{9}$ = 9
16X+24+54X-27-54X=81
16X=84
X= 21 /4
