Answer:

y = -3      x = 7

Step-by-step explanation:

-2x + 9y = -41

(-2x -5y =1) -1            Multiply this equation by -1 to cancel the x

-2x + 9y = -41

+ 2x + 5y = -1            Add both equations

14y =  -42                  Divide both sides by 14

y = -3

Plug -3 in for y into one of the equations

-2x + 9(-3) = -41          Multiply 9(-3)

-2x - 27 = -41

     + 27 + 27              Add 27 to both sides

-2x = -14                      Divide both sides by -2

x = 7

When six times a number is decreased by five, the result is 49. what is the number?
solong [7]
Put this into an equation. Make the missing value "x".
6x - 5 = 49
49 + 5 = 54
54 / 6 =  9 
x = 9.
The missing number is 9.

Hope This Helps You!
Good Luck Studying :)

Given m|n, find the value of x and y.
galben [10]

We know that m ║ n.

Let's first find the value 'x'.

When two lines are parallel, and a transversal is drawn, the angles on the same side of the transversal are equivalent.

This means that (5x + 16)° and (7x + 4)° are equivalent.

Equating them,

5x + 16 = 7x + 4

16 - 4 = 7x - 5x

12 = 2x

x = 12/2

x = 6°

Since we know the value of 'x', let's substitute them into the angles and find out the actual measurements.

5x + 16 = 5 × 6 + 16 = 30 + 16 = 46°.

7x + 4 = 7 × 6 + 4 = 42 + 4 = 46°.

Now let's find the value of 'y'.

If you observe carefully, (7x + 4)° and (y + 6)° form a linear pair.

This means that both those angles should add upto 180°.

Using that theory, the following equation can be framed:

(y + 6)°+ (7x + 4)° = 180°

Since we know the actual value of (7x + 4)°, let's substitute that value and move ahead.

(y + 6)° + 46° = 180°

y + 6 + 46° = 180

y + 52° = 180°

y = 180° - 52°

y = 128°

Therefore, the values of 'x' and 'y' are 46° and 128° respectively.

Hope it helps. :)
