Find the pair of linear equations 2x-y=5 and 5x-y=11.​

Answer:

2x-y=5

2x=5+y

x=5+y/2

5x-y=11

5{5+y/2}-y=11

25+y/2-y=11

25+y/2-2y/2=11

25+y-2y/2=11

25-y/2=11

25-y=11+×2=22

-y=22-25

-y=-3

y=3

Step-by-step explanation:

// Solve equation [2] for the variable y

[2] y = 5x - 11

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

[1] 2x - (5x-11) = 5

[1] -3x = -6

// Solve equation [1] for the variable x

[1] 3x = 6

[1] x = 2

// By now we know this much :

x = 2

y = 5x-11

// Use the x value to solve for y

y = 5(2)-11 = -1

So,

x=2, y = -1
