Question

if (1,3) is the solution of the equation 4x+my=19, find the value of m.​

Answer 1

Answer:

m=5

Step-by-step explanation:

,

$(1,3 ) = (x,y) \\ x = 1 \\ y = 3 \\ 4x + my = 19 \\ 4 \times 1 + m \times 3 = 19 \\ 4 + 3m = 19 \\ 3m = 19 - 4 \\ 3m = 15 \\ m = 15 \div 3 \\ m = 5$

Answer 2

Step-by-step explanation:

4x+my=19

let, x=1, Y=3

Putting the values of X and y in the eqn

4(1) + m(3)=19

4+m3 = 19

m3=19-4

m3 = 15

m = 15/3

m=5
