Question

Can someone help with this?

Nobody has been able to solve this, they keep getting x=8.3.
Answers will be appreciated.

0.2x+2.7x−8.1=6.9+1.1x

Answer 1

Explanation:

0.2x+2.7x−8.1 = - 5.2x and 6.9+1.1x = 8

Ig you add them it would be 2.8

Answer 2

x =
`(25)/(3)`

simplify left side by collecting like terms

2.9x - 8.1 = 6.9 + 1.1x ( subtract 1.1x from both sides )

1.8x - 8.1 = 6.9 ( add 8.1 to both sides )

1.8x = 15 ( multiply both sides by 10 )

18x = 150 ( divide both sides by 18 )

x =
`(150)/(18)` =
`(25)/(3)`
