Answer 1

Verified answer

Explicación paso a paso:

a)3x+10=82

3x= 82-10

3x= 72

x= 72/3

x= 24

b)4=x:5+3

4-3 = x/5

1=x/5

1x5 = x

x=5

c)2x+3x=35

5x= 35

x= 35/5

x=7

d)5x+7=2x+19

5x-2x= 19-7

3x= 12

x= 12/3

x= 4

COMPROBACIÓN

a)3x+10=82

2(24)+10= 82

72 +10 = 82

82 = 82

b)4=x:5+3

4= (5):5 + 3

4 = 1 + 3

4= 4

c)2x+3x=35

2(7)+3(7)= 35

14 + 21 = 35

35 = 35

d)5x+7=2x+19

5(4) + 7 = 2(4) + 19

20 + 7 = 8 + 19

27 = 27
