Question

Find two consecutive even integers whose sum is -50. Which of the following equations could be used to solve the problem? A) 2 x + 2 = -50 B) 2 x = -50 C) 2 x + 1 = -50 D) x^2 + 1= -50

Answer 1

Answer:

$2x+2=-50$

Step-by-step explanation:

$x+2=y\\x+y=-50\\x+x+2=-50\\2x+2=-50$

The equation that can be used to find out $x$ and $y$ is $2x+2=-50$

Answer 2

Answer:

$\mathrm{A}$

Step-by-step explanation:

Two consecutive even integers.

The first integer is even and can be as $x$

The second integer is also even and can be as $x+2$

Their sum is $-50$

$x+x+2=-50$

$2x+2=-50$
