Answer:
Option A and B are correct
Step-by-step explanation:
We have to add here
6x+5y=1.
6x-5y=7
sow e will get 12x=8 , x=8/12=2/3
Option A is correct.
If We substract bottom from furst then
6x+5y=1
-6x+5y=-7
10y=-6
y=-6/10=-3/5
we put y=-3/5 in any equation and find x
6x+5(-3/5)=1
6x=4
x=4/6=2/3
So Option B also correct.
Answer:
4
Step-by-step explanation:
Answer:
21 Students played string instruments
Step-by-step explanation:
58 - 16 = 42, 42 ÷ 2 = 21 so 21 + 21 + 16 = 58. because there are sixteen more wind instruments that means you need to have the wind and string equal and then add 16 more winds which is what i did, if you have 21 string instruments and (21+16) 37 wind instruments then you have 58
