It’s y20 I just did this last night
<span> 2(2x-3y=3)..................4x-6y=6..........equation 1
3(5x+2y=17)
...........15x+6y=51</span>........equation 2
adding equation 1 and equation 2;
19x=57
x=3
2x-3y=3
(2*3)-3y=3
6-3=3y
y=1
The temperature was 65 F at 1:50 P.M.
150 - 110 = 40
40 x 2 = 80
80 - 15 = 65
