x = 12 , y = 9
you set the “x” equations equal to each other to simply and find “x” . once you find “x” you simplify “x+29” ( equals 41) , add it to the “y” equation and set the entire equation (16y - 5 + 41) equal to 180° (16y - 5 + 41 = 180) since that’s what a line is equal to and then solve ! hope i helped :)
