' < ' symbol creates a true sentence when x equals 3 8(3-4x)____7(10-x).
Explanation:
Given:
X=3
8(3-4x)____7 (10-x)
Solution:
The given equation can be divided as LHS and RHS , So
LHS be 8(3-4x)
RHS be 7 (10-x)
Substituting x=3 in the LHS we get
8(3-4(3))
8(3-12)
8(-9)
-72
Substituting x=3 in the LHS we get
7 (10-x)
7 (10-3)
7(7)
49
Hence -72<49. Thus lesser than relation is used.
