$$\frac{x-12}{16}=\frac{5}{2} ;\frac{y+7}{20}=\frac{5}{2}$$

myininaya · Answer

solve for x and for y
then add them together to find x+y

I'M SO CONFUSED.

anonymous · Answer

first solve first equation for x
x - 12            5
-----    =      -
    16              2  
 to eliminate the fraction multiply thru  by 16

x - 12   =   40
x = 52

do a similar thing in y equation to find y then add this value to 52

so y+7=50 which means that y=43? and 43+52=95 and I have my answer. Thanks!
