Question

passo a passo, please:

a) 4(x+3)=2x+1
b) 2-5(x+2)=x+5
c) 5x-4=2(x+6)
d) 2+3(x+1)=2x+6​

Answer 1

Resposta:

d ) (x+1)-2x=-2-3+6 depois mando o resto

Answer 2

a)

4(x+3)=2x+1

4×+12=2×+1

4×-2×=+1-12

2×= -11

×= -11÷2

×= - 5,45

b)

2-5(x+2)=x+5

2-5×-10=×+5

2-10-5=×+5×

-8-5=6×

-13=6×

×=-13÷6

×=-2,1

c)

5x-4=2(x+6)

5×-4=2×+12

5×-2×=12+4

3×=16

×=16÷3

×=5,3

d)

2+3(x+1)=2x+6

2+3×+3=2×+6

2+3-6=2×-3×

5-6=-×

-1=-×

×= 1
