The sum of two numbers is 12, when the larger number is added to 5 times the smaller , the sum is 32 find the numbers?

So x plus y = 12. Okay. Let's say x is the larger one. So x plus 5y = 32. Let's do guess and check. 4 + 8. Okay. 8 + 20 = 28. Nope. 5 + 7? Okay. 7 + 25 = 32. So the answer is 7 and 5. Use your head. I'm only in fifth grade and i could figure it out. I believe in you!! xo
Okay so i figured out what the equation was. So... x, the larger number let's say, plus y, the smaller number, so
5y + x = 32 and x + y = 12. Yeah Idk that's all i got

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
