How many solutions does this system have?
42 - 12y = 24
62 - 12y = 24

I think you may have formatted this question incorrectly as there are two separate equations for the same variable. However, the equations give two different results for the variable and aren't a system of equations at all.

If you only wanted to know the y for both then here it is.

y = 3/2

y = 19/6

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,
