Answer: x = 13, y = 8

Explanation:

Since 10x-9 and 4x+7 are supplementary (equal to 180)

you set up this equation:

10x-9+4x+7=180

combine like terms

14x-2=180

simplify

14x=182

x=13

setup for y is easy since we now have x

12y+25+4x+7=180

substitute 13 for x

12y+25+4(13)+7=180

simplify

12y+25+52+7=180

simplify further

12y+84=180

simplify again

12y=96

finally, divide

y=8
