Question

resolva as equaçoes
a=2x+1=5
b=3x+2=x+8
c=x\4=16

Answer 1

Olá

a) 2x +1 = 5

2x = 5 - 1

2x = 4

x = 4/2 ÷ 2

x = 2

b) 3x + 2 = x + 8

3x - x = 8 - 2

2x = 6

x = 6/2 ÷ 2

x = 3

c) x/4 = 16 =mmc de 4 ,1 =4

x = 64/4==>elimine o denominador

x = 64

Espero ter ajudado

Answer 2

a) 2x+1=5

   2x= 5-4

    x= 1/2

B) 3X+2=X+8

3X - X= 8-2

2X=6

X=6/2

X=3

C) X/4=16

X=16X4

X= 64
