THIS IS EASY MAN
33X+38X=284 ADD VARIABLES "X"
71X=284 SIMPLIFY
X=284/71 SIMPLE DIVISION
X=4
CHECK YOURS ANSWER. IS THIS CORRECT FOR X? ASK YOURSELF
ORIGINAL EQUATION IS 33X+38X=284
PUT THE VALE OF X=4 IN THE EQUATION
33(4)+38(4)=284
132+152=284
284=284
HENCE PROVED THAT L.H.S= R.H.S

33x+38x=284
71x=284
71x/71=284/71
x=284/71
x=4
71x=284
71x/71=284/71
x=284/71
x=4
