5(x+5)=65

X=8

5*x=5x
5*5=25

65-25=40
40/5=8 ("when you divide do not touch the x")

Hope this helps! 

What is x
well first use distributive property
5x+25=65
Next subtract 25 on each side 
5x=40
Next divide 5 on both side which equal 8 so
x=8

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
