Use the elimination method to solve the system of equations. Choose the correct ordered pair. -x + y = -2
2x - 3y = 4

A. (3, 1)
B. (4, 2)
C. (2, 0)
D. (5, 3)

C. (2, 0)

Step-by-step explanation:

-x + y = -2

2x - 3y = 4

Multiply both sides of the first equation by 2.

Write the second equation below it and add them.

        -2x + 2y = -4

(+)       2x - 3y = 4

                  -y = 0

y = 0

Start again with the original equations.

Multiply both sides of the first equation by 3. Write the second original equation below it and add them.

      -3x + 3y = -6

(+)     2x - 3y = 4

          -x      = -2

x = 2

C. (2, 0)

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
