Question

x + 2y = 3/2
2x+y=3/2
solve by eliminating and substantial method..​

Answer 1

Step-by-step explanation:

by elimination method:

x+2y=3/2

2(x+2y)=3

2x+4y=3..........(1)

2x+y=3/2

2(2x+y)=3

4x+2y=3..........(2)

Multiplying eq1 by 2

2(2x+4y)=2×3

4x+8y=6..........(3)

subtracting eq2 from eq3

4x+8y=6

4x+2y=3

(-) (-) (-)

6y=3

y=3/6

y=1/2

putting value of y in eq1

2x+4(1/2)=3

2x+2=3

2x=3-2

2x=1

x=1/2

thus the value of x is 1/2 and value of y is 1/2
