X and y are gonna be the variables you will solve when you do it by substitution. x=3 and y=11
3% x
100 $700
Cross multiply and divide your only number which is 100.. 3 is your percent so it has to be over 100 and your x is your variable, your unknown number over $700 Set it up like a Fraction ! 3 times 700= 2,100 divide it by 100 which is equaled to 21 So 21 is like your percent !! Hope this helped...
