Question

A) 6(×-3)=36
B) 4(×+2)=48
C) 3(3×-9)=27
D) 5(2×+4)=60
E) 6(×-4)=3(×+2)
F) 5(2×-6=2(4×+8)

Answer 1

Resposta:

a- 6x-18= 36

6x=36+18

6x= 54

x= 54/6

x= 9

b- 4x+8=48

4x=48-8

4x=40

x= 40/4

x= 10

c- 9x-27=27

9x=27+27

9×= 54

x= 54/9

×=6

d- 10x+20=60

10×=60-20

10×=40

×=40/10

×=4

e- 6x-24= 3×+6

6×-3×=6+24

3×=30

×=30/3

×=10

f- 10x-30= 8x+16

10×-8×=16+30

2×=46

×=46/2

×=23
