Question

A-) -5X+45-89 =-90+41

B-) 20-80+2X=10

C-) 19-2X-13=10-20

D-)2X+3X+9=8 (6-X)

E-) 4 (X-10) -2 (X-5)=0

F-) 13+4 (2X-1)= 5 (X+2)

G-) 3X-17=2X+5

Answer 1

A) -5X = -90 +41 -45 +89

-5X = -135 + 130

-5X = -5 .( -1)

X = 1

B) 2X = 10  +80 -20

2X = 90 -20

2X = 70

X = 35

C) -2X = 10 -20 +13 -19

-2X = -39 + 23

-2X = -16 . (-1)

X= 8

D) 2X + 3X +9 = 48 -8X

2X +3X +8X = 48 + 9

13X = 39

X = 3

E) 4X - 40 -2X -10 = 0

4X -2X = 10 +40

2X = 50

X = 25

F) 13 +8X -4 = 5X +10

8X -5X = 10 +4 -13

3X = 14 - 13

3X = 1

X = $\frac{1}{3}$

G) 3X -2X = 5 +17

X = 12

Espero ter te ajudado! Bons estudos !! :3
