Question

Write any two solutions of equation : 7x + 3y = 10.​

Answer 1

7x - 3ʏ = 10

ᴇǫᴜᴀᴛɪᴏɴ↑↑↑↑↑

___________________________

// Solve equation [2] for the variable y

[2] 4y = 12

[2] y = 3

___________________________

// Plug this in for variable y in equation [1]

[1] 7x - 3•(3) = 10

[1] 7x = 19

___________________________

// Solve equation [1] for the variable x

[1] 7x = 19

[1] x = 19/7

___________________________

// By now we know this much :

x = 19/7

y = 3

We are done

___________________________

Solution :

{x,y} = {19/7,3}
