yes but you cannot derive the answer.....ill show you.....if you will solve the equation
31+x=x+31 x=x+31-31 x
31+x=x+31 so, use additive property to move 31 to the right side of the equation x=x+31-31 right after the x also ,,,so you cannot find the answer cause ma cancel man ang both unless if 1 x ra siya
ooohh,
thank you po ^^
