Question

solve the
method
equations by elimination method x+2y=11 and x-y=2.​

Answer 1

Answer: x=5 and y=3

Step-by-step explanation:

x+2y=11------- 1

x-y=2-----------2

Multiply equ 2 by 2:

x+2y=11

2x-2y=4

------------

3x = 15

x=15/3

x=5

Substitute x=5 in equ 1

(5)+2y=11

2y=11-5

2y=6

y=6/2

y=3
