(20x - 10) + (56 -12x) >/= 3
*Eliminate fractions > rewrite the inequality without parenthesis >
20x - 10 + 56 -12x >/ = 3
First: combine "like" terms >
20x - 12x - 10 + 56 >/ = 3
8x + 46 >/= 3
Sec: subtract 46 from both sides >
8x + 46 - 46 >/= 3 - 46
8x >/= - 43
Third: solve for "x" by isolating it on one side > divide everything by 8 >
8x/8 >/= - 43/8
x >/= -43/8

(20x - 10) + (56 -12x) > or = 3
20x - 10 + 56 - 12x > or = 3
8x + 46 > or = 3
Subtracting 46 from both sides
8x > or = - 43
Dividing both sides by 8
x > or = - 43/8

(20x - 10) + (56 -12x) > = 3
20x - 10 + 56 -12x > = 3
8x + 46 > = 3
8x + 46 - 46 > = 3 - 46
8x > = - 43
x >= - 43/8
you do the math
Cody you're right...

combine like values
20x - 12x + 56 - 10 > or = 3
8x + 46 > or = 3
8x > or = - 43
x > or = -5.375

i think just treat it as an equation (for get about > and just think about = )
then just solve it, and dont for get about >
I get
