Question

How do you solve this problem 8+2x<6x-20

I tried to subtract the 2 from 6 and work my way through but it only gave a -1.5

Answer 1

add 20 to both sides: 28+2x&lt;6x

subtract 2x from both sides: 28&lt;4x

divide by 4: 7&lt;x

Answer 2

8 + 2x &lt; 6x - 20

2x - 6x &lt; -20 -8

-4x &lt; -28

divide both sides by -4, remember that you have to change the sign when you do this

x &gt; 7

Answer 3

8+2x=6x-20

  -2x  -2x

8=4x-20

+20  +20

28=4x

/4  /4

7=x
