Question

A) 2x+1= 6
B) 3x+5x= 16
C) X+3x= 2x+8
D) 10x-2= 8

Answer 1

Resposta:

Explicação passo a passo:

A) 2x+1= 6

2x = 6-1

2x = 5

x = 5/2

B) 3x+5x= 16

8x = 16

x = 16/8

x = 2

C) X+3x= 2x+8

4x = 2x+8

4x - 2x = 8

2x = 8

x = 8/2

x = 4

D) 10x-2= 8

10x = 8+2

10x = 10

X = 10/10

X = 1
