5 is the correct answer.
To prove it, subtract 5 from 18 - You'll get 13.
5 x 2 + 3 = 13.
You can approximate the square root of 30 by taking the square root of a number close to it. This is called local linearization. You can take the square root of 36, which is 6, and the square root of 25, which is 5, and state that the square root of 30 is approximately somewhere between 5 and 6

Answer:
x=-33/5 y=29/5
Step-by-step explanation:
Let's solve your system by substitution.
3x+y=−14;2x−y=−19
Solve
3x+y=−14 for y:
3x+y=−14
3x+y+−3x=−14+−3x(Add-3x to both sides)
y=−3x−14
Next is to substitute −3x−14 in for y 2x−y=−19:
2x−y=−19
2x−(−3x−14)=−19
5x+14=−19(Simplify both sides of the equation)
5x+14+−14=−19+−14(Add -14 to both sides)
5x=−33 Dived both sides by 5
5x/5=-33/3
x=−33/5 since you can't dived and a fraction is another form of division you keep it this way.
Step: Substitute -33/5 for x in y=−3x−14:
y=−3x−14
y=−3(-33/5)-14
y=29/5
(Simplify both sides of the equation)(since you can't dived and a fraction is another form of division you keep it this way.)
So
x=-33/5 and y=29/5
Pls mark brailest this took me a long time to write out lol. Hope this truly helps! Send a heart if so, so I can keep spreading the help!
