Answers
Answer:
24
Step-by-step explanation:
3×4+4×3=24
it is the correct answer
Given : Point (4,3)
To Find : Point (4,3) lies on which of the below line
3x+7y=27
7x+2y=47
3x+4y=24
5x-4y=1
Solution:
Any point lying on a line will satisfy the Equation of the line.
3x+7y=27
Substitute x= 4 and y = 3 in LHS
LHS
= 3(4) + 7(3)
= 12 + 21
= 33
≠ RHS
7x+2y=47
Substitute x= 4 and y = 3 in LHS
LHS
= 7(4) + 2(3)
=28 + 6
= 34
≠ RHS
3x+4y=24
Substitute x= 4 and y = 3 in LHS
LHS
= 3(4) + 4(3)
= 12 + 12
= 24
= RHS
Hence Point (4,3) lies on the line 3x+4y=24
5x-4y=1
Substitute x= 4 and y = 3 in LHS
LHS
= 5(4) - 4(3)
= 20 - 12
= 8
≠ RHS
so Point (4,3) lies on the line 3x+4y=24
