Explanation:
1
[One] - [minus] [the product of]
4
[four] and
x
, [unknown number].
4
x
is the product of 4 and x
(
4
⋅
x
)
.
2=2
63= 3* 3* 7
14= 2*7
LCM (2,63,14)= 2*3*3*7= 126
The least common multiple (LCM) of 2, 63, and 14 is 126~
Draw the lines x = 3 and y = -1
There will be a region formed in the middle.
Shade the outside of this region.
