Answer:
2x=72
Step-by-step explanation:
this is a algebra problem.
you need to find what the x is.
x is a unknown #
to do that:
2x=72...........the 2 and x are multiplying together, you need to do the opposite of multiply which is divide.
divide BOTH sides of this equation by 2 to x alone on one side of thew equal sign
2x/2 = x multiplying by 2 and divding by 2 cancel out, leaving you with just the variable ...x
72/2=36
now onthe other side, just do the math 72 divde by 2 equals 36
x = 36
so, now multpiy 2 times the # you found you should 72
2(36) = 72 or 2 x 36 = 72
both sides are equal
try doing it to the other 3 answer you won't the same answer.
