so we will use n= total number of magazines each 

we start with $2n and $1.50n

then we add $2 and $1.50 =  $3.50n

with that we put $3.50 into an equation  $3.50n = $10.50

so now lets get rid of those decimals by taking 3.5 and doubling it to become 7  after that we need to double 10.5 to 21 

so our new equation is 7n = 21

lets get n be itself by dividing 7 from both sides so that on the side with 7n the 7 cancels out

Finally n=21/7  which equals 3 

so they both both 3 magazines each so if your looking for the total number of magazines between then they got 6 magazines
