Question

4x+y/3=8/3 x/2+3y/4=-5/2 by cross multiplication

Answer 1

answer

1. x=1
2. y=-4

step by step explanation

12x+y=8......(1)

2x+3y=-10......(2)

equation 1 is multiplied by 3 and then subtraction between (1)&(2)

34x=34

x=1

putting in equation (2)

2+3y=-10

3y =-12

y=-4

please make me a brainlist answer for the question

Answer 2

Answer:

X = 1 and Y = -4

Step-by-step explanation:

4x +y/3=8/3

12x/3+y/3=8/3

12x +y=8  ..(1)

x/2+3y/4=-5/2

2x/4+3y/4=-5/2

2x+3y=-10 ..(2)

by cross multiplication method

     X                Y                    1

1            -8                  12                  1

3            10                  2                   3  

x/(1*10)+24         =           y/(-8 *2)-120          =           1/(12*3)-2

x/34    =    y/-136      =      1/34  

x=34/34          y=-136/34

x =1 and y = -4
