Question

Determine o valor das incógnitas apresentadas
A) 2(x+5)-4=26
B) 4(2x-1)=3(x+2)
C) 5(2x-1)=3(x+10)
D) 3(x+2)-1=2(x+3)-7

Answer 1

Resposta:

a) x= 10

b) x= 2

c) x= 5

d) x= 1

Explicação passo-a-passo:

a) 2x+10-4= 26

2x+6= 26

2x= 26-6

x= 20/2

x=10

b) 8x-4= 3x+6

8x-3x= 6+4

5x= 10

x= 10/5

x= 2

c) 10x-5= 3x+30

10x-3x= 30+5

7x= 35

x= 35/7

x= 5

d) 6x+6-1= 2x+6-7

6x-2x= 6-7+5

4x= 4

x= 4/4

x= 1
