Answer:

Option 2: 2x + 2 = 72

Answer 2

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.
