Answer 1

Olá

Vamos lá

(A)X+=18
x=18

(B)1-X=4
-x=4-1
-x=3
x=-3

(C)18=2-5X
5x=2-18
5x=-16
x=-16/5

(D)2X-5=5X+4
5x-2x=4+5
3x=9
x=9/3
x=3
(E)
1-3X+8-5X=9-12X+5
-3x-5x+12x=9+5-1-8
4x=5
x=5/4

(F)X-8=-5
x=-5+8
x=3

(G)5X-4-11 = errada

(H)-4=3+10X
10x=-4-3
10x=-7
x=-7/10


(I)10X-17+3X=7X+5-5X
10x+3x-7x+5x=5+17
18x-7x=22
11x=22
x=22/11
x=2

(J)3-2(X+3)=X-18
3-2x-6=x-18
2x+x=3-6+18
3x=15
x=15/3
x=5

(K)3(X-4)=-1-1(3X-1)
3x-12=-1-3x+1
3x+3x=-1+1+12
6x=12
x=12/6
x=2

(L)50+2(3X-4)=2(3X-3)+26
50+6x-8=6x-6+26
6x-6x=-6+26-50+8
