Which best describes the error in solving the system of linear equations 2x+y=5
3x-2y=4

I do not know if this is what you meant

x=2

y=1

Step-by-step explanation:

2x+y=5

3x-2y=4

multiply by 2

4x+2y=10

3x-2y=4

add

7x=14

divide

x=2

substitute

2(2)+y=5

3x-2y=4

solve

y=1

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

ensure that you have copied down this problem correctly.   .

answer

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,
