Question

What is the solution of x+4y=3; 3x=2y+2?​

Answer 1

Step-by-step explanation:

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

3x=2y+2 .. Rearranging

3x-2y=2 ....(2)

Multiplying equ (1) by 2 & equ (2) by 4 we get,

2x+8y=6 ...(3)

12x-8y=8 ...(4)

Adding equ (3) & equ (4)

2x+8y=6

+ 12x-8y=8

14x+0y=14

14x=14

x= 14

14

x= 1

Substituting the value of x=1 in equ (1)

x+4y=3

1+4y=3

4y=3-1

4y = 2

y= 2

4

y= 1

2

(x,y) = ( 1,1/2 )
