Find the solution for a system of equations by elimination
3x – 6y = 12
5x - 2y = 10

y=2, x=1

Step-by-step explanation:

3x-6y=12(x2)

5x-2y=10(x6)

Eliminate y

6x-12y=12

30x-12y=60

-24x =-48

divide both sides by -24

-24x/-24=-48/-24

y=2

to get our x

3x-6(2)=12

3x-12=12

3x=12+12

3x=24(divide both sides by 3)

x=1

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

answer: r there any options?
