Solve the equation x – 5 = 0.1(x + 5) for x. Round your answer to the nearest hundredth.

Nadusha1986 [10]

Answer:

x=6.111....

Step-by-step explanation:

x-5=0.1(x+5)

distribute 0.1 into (x+5)

x-5=0.1x+0.5

subtract 0.1x on both sides

x-0.1x-5=0.5

combine like terms

0.9x-5=0.5

add -5 on both sides

0.9x=5.5

divide both sides by 0.9

$\frac{0.9x}{0.9} =\frac{5.5}{0.9}$

x=55/9 or 6.11111.......

hope this helps
