Question

Solve the following system of linear equations graphically 2x-y=1; x-y =-1 shade the region bounded by above line and in y axis

Answer 1

Answer:

0

Step-by-step explanation:

2x-y=1. ―1equation

x-y=-1. ―2equation

add equation 1 and 2

2x-y=1

+. x-y=-1

-y ,-y cancel because same sine

answer is 3x=0

x=0÷3

x=0

Answer 2

x=1

Step-by-step explanation:

x-y=2

2x-y=1

-x=1

x=1
