Solve the inequality
8x less than 6x + 5
I some how managed to get to 8x - 6x less than 5 and then
2x less than 5.
What do i do after this or have i solved it so to speak. I dont think i have. Help!
Thankyou (if you could show me your method much appreciated)

8x < 6x + 5
8x - 6x < 5
2x < 5
You got all that right ;-)
All you have to do now is divide both sides by 2 to get x by itself, since 2x/2 = x
So, 2x / 2 < 5 / 2
x < 2.5
Hope that helps. Enjoy :)

8x < 6x + 5
2x < 5 (after taking 6x from both sides)
x < 5 / 2 (after dividing both sides by 2)

8x < 6x + 5
8x - 6x < 5
2x < 5
x < 5/2
x < 2.5

Rplace the less than with =
8x=6x+5
2x=5
x = 2.5
replace = with less than
x<2.5

ok nicely what you may desire to do first is multiply the three to the different factor. you will get 2x<30. then you divide 2 to the different factor and get x<15 ... in actuality, you think of the inequality sign is an equivalent till you're multiplying or dividing with the help of a adverse by way of fact the sign will turn. which incorporate : 2x/-3 < 10 2x > -30 x > -15

first..you have to re-write the equation in mathematical sentence form..
6x + 5 < 8x
then..you transpose 5 to the other side..
6x < 8x - 5
to solve the equation easily..transpose 8x to 6x which gives you -2x..
-2x < -5
divide both sides by -2..
the answer is..
x < 2.5

8x<6x+5
8x-6x<5
2x<5 (time both side by 1/2)
x<5/2

8x < 6x+5
8x-6x < 5
2x < 5
x < (5/2)
x < 2.5
Therfe for x lies from negative(infinity) to 2.5
Thus problem is solved

8x<6x+5
then, subtracting 6x from both sides
2x<5
then, divide both sides by 2
x<5/2
