Please explain I’ll give you brainliest just explain how you did it. This is confusing for me. Explain how you did it I wanna know.

(55,9) Explanation is below.

Step-by-step explanation:

What you want to do is try to mutliply one of your equations so that either y or x will be canceled out.

Here is the example:

Say you want to get rid of x, you can multiply the first equation: x-5y=10 by -2 to match the second equation: -2x+6y=-16.

Therefore, the first equation would become -2(x-5y=10)=> -2x+10y=-20

Then subtract the first equation from the second:

 (-2x+6y= -16)

- (-2x+10y = -20)

=> 0x-4y= -36

Simplify and then you get y=9.

To find x, plug in y into one of the equations: x-5(9)=10 => x-45=10 => x=55

Sorry if I didn't explain it correctly.

Have a nice day! :D

can you me with homework?

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
