Question

-5x+6y=28
-9x+5y=4 x and y vaule

Answer 1

X and Y value is : x=4; y=8

Given:

    Equation 1 =    -5x+6y=28

     Equation 2 =   c

To find:

       X and Y

Solution:

Step 1: Multiply equation 1 by 9

(-5x+6y=28)*9 = -45x+54y=252

Step 2: Multiply equation 2 by -5

( -9x+5y=4)*(-5) = 45x-25y= -20

Step 3: On solving both the equation we get y=8

Step 4: Substitute value of y in equation 2

-9x+5*(8)=4

9x=36

x=4

Hence, x=4; y=8
