3 0

Answer:

x+3y = 6

or, x = 6-3y.................(1)

3x+5y =6..........(2)

Substituting x = 6-3y in equation (2),

3 (6 - 3 y)+5 y =6

or, 18 - 9y +5y=6

or, y = 3

x = 6 - 3y = 6- 3.-3 = -3

Ray ML and MN are perpendicular. ray MP ia an angel bisector. find the value of x .​
bulgar [2K]

Answer: x = 15

Step-by-step explanation:

First, we will have to acknowledge that Angle M is a complementary angle (that means that it is 90 degrees) meaning that 2x° + 4x° will equal 90 degrees. So, let’s set up this equation.

90 = 2x + 4x

90 = 6x

\frac{90}{6} = \frac{6x}{6}

15 = x

Therefore, the x is 15.
