T+b=280
2t+3b=660
eliminate tacos
multiply top equation by -2 and add to botom one
-2t-2b=-560
<u>2t+3b=660 +</u>
0t+1b=100
b=100
100 burritos
sub back
t+b=280
t+100=280
minus 100
t=180
180 tacos and 100 burritos

Answer:
4x+11
Step-by-step explanation:
3 times 2x equals 6x
3 times 7 equals 21
(put that together) = 6x+21
2 times x equals 2x
2 times 5 equals 10
(put that together) = 2x+10
(put both of those equations together) = 6x+21-2-10 (minus 10 because u r subtracting 2+10 from 6x+21, so u have to subtract 2-10)
group the x's together.
so it would equal 6x-2x=4x+21-10
21-10 equals 11
so, answer is 4x+11
hope this helps. sorry if I didn't quite explain this so well, I'm not good with explaining how I got my work
