Question

Find x from 5 ( 2x + 1 ) = 27

Answer 1

Answer:-

Given equation:-

$\\ \rm\longmapsto 5(2x+1)=27$

• Multiply on left side.

$\\ \rm\longmapsto 10x+5=27$

• Take 5to right side.

$\\ \rm\longmapsto 10x=27-5$

$\\ \rm\longmapsto 10x=22$

• Take 10to right side

$\\ \rm\longmapsto x=\dfrac{22}{10}$

• Convert to decimals

$\\ \rm\longmapsto x=2.2$

Answer 2

Answer:

5 ( 2x + 1 ) =28

2x + 1 = 28 ÷5

2x + 1 = 5,6

2x = 5,6 - 1

2x = 4,6

x = 4,6 ÷ 2

x = 2,3
