Question

x×[ y+(4)] = [ (5)] ×(-7)]+ +[5× z] find the value of x,y,z from the following​

Answer 1

Answer:

x[y+(4)] = [(5)×(-7)]+[5×z] ________ 1

we now simplify RHS using distributive property

[(5)×(-7)] + [5×z]

5×(-7+z)

now expression 1 gives

x[y+(4)] = 5(-7+z)

comparing both sides we get

x= 5 , y= -7 , z= 4
