Solve the system of equations below:
5x-2y=18
3x+3y=15

Answer : The value of x and y is, 4 and 1 respectively.

Step-by-step explanation :

The given equations are:

      ..........(1)

      ..........(2)

Using substitution method,

     ...........(3)

Now putting equation 3 in 2, we get the value of y.

Now putting value of y in equation 3, we get the value of x.

Thus, the value of x and y is, 4 and 1 respectively.

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,
