Question

solve the following simultaneous equation. x+y=11, x-y=5​

Answer 1

Step-by-step explanation:

y = 3

x = 8

this is the value ofx and y I hope you understand

Answer 2

Answer:

x=8,y=3

Step-by-step explanation:

// Solve equation [2] for the variable x

[2] x = y + 5

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

[1] (y +5) + y = 11

[1] 2y = 6

// Solve equation [1] for the variable y

[1] 2y = 6

[1] y = 3

// By now we know this much :

x = y+5

y = 3

// Use the y value to solve for x

x = (3)+5 = 8

hope this is helpful for you
