Answer:
Step-by-step explanation:
|2x-3|≤9
so -9≤2x-3≤9
add 3 to each inequality
-6≤2x≤12
divide by 2
-3≤x≤6
4 legged tables : x
3 legged stools : y
x + y = 20 y= 20 - x
4x + 3y = 68
Replace y by 20 - x so we only have one letter
4x + 3(20 - x) =68
4x + 60 - 3x =68
x + 60 = 68
x = 8
To find y replace x by 8
y = 20 - 8
y = 12
So you have 8 four legged chairs and 12 three legged stools.
