Answer:

the two numbers are 19 and 6

Step-by-step explanation:

so we know that there are two numbers that added together give us 25

x+x=25

one of the numbers is twice the amount of the second plus 7

(2x+7)+x=25

simplify 2x+7+x

3x+7=25

subtract 7 from both sides

3x=18

divide 3 by both sides

x=6

and there is your answer.

What is the solution to the system of equations below?

Free_Kalibri [48]

Answer: Infinite solutions.

Step-by-step explanation:

$y=-2x-6\\2y=-4x-12$

Plug the value of y into the second equation.

$\\ 2(-2x-6)=-4x-12\\-4x-12=-4x-12$

Add 12 on both sides.

$-4x-12+12=-4x-12+12\\-4x=-4x$

Add 4x on both sides.

$-4x+4x=-4x+4x$

$0=0$
