solve it the same way as if you'd solve a regular equation
try to get all the variable terms onto one side and the constant terms on the other.
moving the x to the right side, i would subtract by 3x
3x-2-3x≤ 4x+8-3x
since
3x-3x= 0
then
-2 ≤ 4x -3x +8
add up like terms( or subtract)
-2 ≤ (4x -3x) +8
-2 ≤ x +8
now move the constants onto the left side, this could be done by subtracting 8 to boh sides
-2 -8 ≤ x +8-8
8-8=0
so
-2-8 ≤ x
add up like terms(or subtract)
-10 ≤ x
and flip it if you want the x term to be on the left
