Solve this system of equations: X=? Y=? ( JUST WRITE THE NUMBER ANSWERS WITH A COMMA BETWEEN THEM)
hjlf

Answer:

Therefore the Final Solution is

x = 2 and y = 4

( 2 , 4 )

Step-by-step explanation:

Given:

y=2x                ...............Equation ( 1 )

x=-y+6         ................Equation ( 2 )

To Find:

x = ?

y = ?

Solution:

Substitute Equation  ( 1 ) in Equation ( 2 ) we get

x=-2x+6\\\\3x=6\\\\3x=6\\\\x=\frac{6}{3} \\\\\therefore x =2

Now Substituting x = 2 in Equation ( 1 ) we get

y =2\times 2\\\\\therefore y=4

Therefore the Final Solution is

x = 2 and y = 4

( 2 , 4 )

What is m∠ MHJ?<br> 35<br> 50<br> 72.5<br> 92.5
NNADVOKAT [17]

Answer:

50

Step-by-step explanation:

MHJ and LHK are vertical angles, which means they are equal

2x-20 = x+15

Subtract x from each side

2x-20-x = x+15-x

x-20 = 15

Add 20 to each side

x-20+20 = 15+20

x = 35

We want to find MHJ

MHJ =2x-20

        =2(35) -20

       = 70 -20

      = 50
