Question

Solve 2X minus Y +4 equal to 0 and 3X plus 2Y minus one equals 0

Answer 1

Step-by-step explanation:

2x-y+4=0

2x-y=-4............eq.no.1

3x+2y=0...........eq. no. 2

by LCM of x Co efficients

6x-3y=-4........eq. no. 3

6x+6y=0..........eq. no. 4

by solving equations 3and 4

6x-3y=-4

6x+6y=0

- - -

0+9y=-4

Therefore

y=-4/9

substitute y=-4/9 in equation 4

6x+6(-4/9)=0

6x+2(-4/3)=0

6x+(-8/3)=0

6x-8/3=0

6x=8/3

x=48/3

x=18..

x=18,y=-4/9
