find the value of x and y
x+y=12
45x+52y=561
a sporting goods store sold right hand and left hand batting gloves.12 were sold in a one month period for $561.right handed gloves are $45 and left handed gloves are $52.how many of each were sold? please show work

The equations look fine.

x=12-y

Substitute this term for x in the second equation and solve for y. Put that value in the first equation to find x. Check by putting both values in the second equation.

I hope this helps. Thanks for asking.
