Let's say "the second number" is y so y= 7(x) And x+y= 32
you would plug in y=7x into x+y=32 and that would look like this....x+7x=32
then you would add the x's and that would look like.... 8x=32 then you would divide 32/8 and get x =4 to find y, you just plug in x=4 into x+y=32
but I did most of the work so you can find y ;)
its not that hard... im sure you can do that;))))
