Question

if (a,4)lies on the graph of 3x+y=10 then yhe value of 'a' is
2
1​

Answer 1

Answer:

a = 2

Step-by-step explanation:

Given that (a,4) lies on 3x + y = 10.

So, 3 × a + 4 = 10

=> 3a = 10 - 4 = 6

=> a = 6/3 = 2

Answer 2

Answer:

answer is a = 2

Step-by-step explanation:

as 'a' is in the place x co ordinate and 4 is in the place of y co ordinate i think we can substitute those values in the given equation

3x + y = 10

3 (a) +4 =10

3a = 10 -4

3a = 6

a = 6/3

a = 2
