Solve for x. Collect xs on the LEFT side. The solution should be presented with x first, the correct inequality symbol, then the number.

x + 4 - 8x - 1 > 3(x - 2)
- 7x + 3 > 3x - 6
- 7x + 3 + 7x > 3x - 6 + 7x
3 > 10x - 6
3 + 6 > 10x - 6 + 6
9 > 10x
9 / 10 > 10x / 10

x + 4 – 8x – 1 > 3(x – 2)
combine terms on left and disrtibute the 3 on the right
-7x + 3 > 3x - 6
subtract 3x from both sides
-10x + 3 > -6
subtract 3 from both sides
-10x > -9
divide by -10 and switch the inequality sign (because you're dividing by a negative number) and get
x < 9/10
Hope this helps!

Let's solve this step by step:
Given:
x+4-8x-1 > 3(x-2)
Simplifying the left side and expanding the right side, we get:
-7x+3 > 3x-6
-7x+3+7x+6>3x+7x-6+6
9>10x
Dividing by 10 on both sides, we get:
9/10 > x or
x < 9/10

x>1
x+4-8x-1>3(x-2)
Simplify the inequality
-7X+3 > 3x-6
Collect like terms
-10x>-9
divide by coeffecent
(-10x)/-10 > -9/-10
gives the answer
x<9/10
Which mean any value of x greater then one will make the inequality true

expand
x+4-8x-1>3x-6
combine
-7x+3=3x-6
subtract 3x from each side
subtract 3 from each side
-10x>-9
divide both sides by -10 (since negative switch > sign to <)
x<-9/10
