7 + X + 7+17+7 + X + 7 equals 100 what does X equal

X=27.5

First combine like terms

Then subtract 45 from each side

Then divide by 2

the answer is 27.5

Step-by-step explanation:

first you add all the like terms

7+7+17+7+7=45

then you subtract 45 from 100

100-45=55

then you know that the two varibles will equal 55 so the you divide 55 by 2

55/2 = 27.5
