Question

X + 1/2y = 2 ; 3x - y = 1

Answer 1

Step-by-step explanation:

x+ 0.5y =2 ..........eqn1

3x - y =1 .........eqn2

multiply eqn2 by 0.5 then

x+0.5y =2

1.5x - 0.5y=0.5

we get

2.5x = 2.5

x=1

now

1+0.5y =2

so

y=2

Answer 2

Step-by-step explanation:

2x+1 /y =2

2x-2y= -1

6x-2y=2

4x=3

x=3/4
