Answer 2

Answer: HEY MATE HOPE IT HELPS YOU TOO UNDERSTAND....

x =-3/4, y=2/3 and z=-5/6

verify (X * (y +z) = X * y + X *z​

taking LHS

X*(Y+Z)= 3/4(2/3+(-5/6)

            = [3/4*2/3] + [ 3/4*-5*6]

use BODMAS{bracket open division, multiplication, addition, subtraction

            =[1/2]+[-9/10]

            =1/2-9/10

take LCM of 2 and 10 which is 10

so no we will multipy 5 by 1/2 in both the sides

            =5-9/10

            =-4/10

    lhs    =-2/5

now we will take RHS

X * y + X *z​=[3/4*2/3] + [ 3/4*-5*6]

use BODMAS{bracket open division, multiplication, addition, subtraction

            =[1/2]+[-9/10]

            =1/2-9/10

take LCM of 2 and 10 which is 10

so no we will multipy 5 by 1/2 in both the sides

            =5-9/10

            = -4/10

rhs         = -2/5

now we can see that LHS=RHS
