Question

Resolva a equação em R
A) 23x+2=2
B) 12-7+4x=25
C) 5x-3x=20
D) 4x+10=45-3x

Answer 1

Resposta:

a) 23x + 2 = 2

23x = 2 - 2

23x = 0

x = 0.

b) 12 - 7 + 4x = 25

5 + 4x = 25

4x = 25 - 5

4x = 20

x = 20/4

x = 5.

c) 5x - 3x = 20

2x = 20

x = 20/2

x = 10.

d)  4x+10=45-3x

4x + 3x = 45 - 10

7x = 35

x = 35/7

x = 5.

Answer 2

Resposta:A) 23x+2=2

23x=0

X=0

B) 12-7+4x=25

4×=25-12+7

4×=20

×=20/4

×=5

C) 5x-3x=20

2×=20

×=20/2

×=10

D) 4x+10=45-3x

7×=35

×=35/7

×=5
