Answer 1

Explicație pas cu pas:

A) x=33-19

X=14

B)2x=27-13

2x=14

X=14:2

X=7

C)3x-x=46

2x=46

X=46:2

X=13

D)7+13=2x-x

20=x

E)x-3=8*5

X-3=40

X=40+3

X=43

F)x-12=120:6

X-12=20

X=20+12

X=32

G)9*3+9x=63

27+9x=63

9x=63-27

9x=36

X=36:9

X=4

H)2x+10+3x=75

5x+10=75

5x=75-10

5x=65

5x=65:5

X=13

I)3x+3+2x-2=56

5x+1=56

5x=56-1

5x=55

X=55:5

X=11
