Answer:

x equals 6 and y equals -8

Step-by-step explanation:

y = 1/3 x - 10 _____(1)

2x + y = 4 ________(2)

put (1) into (2)

2x + 1/3 x - 10 = 4

multiply through by 3

6x + x - 30 = 12

7x - 30 = 12

7x = 42

x = 42/7

x equals 6

put x = 6 into (1)

y = 1/3x - 10

y= 1/3 (6) - 10

y = 2 - 10

y = -8

0.26, mathematically is like saying 26% of

The answer is 19.24

You'll notice if you type 74 x 0.50 (which is 50%) you will get 37 -- exactly half of  74

-7x + 4y =10<br><br> -5x + 3y = 8
Margaret [11]

Answer:

x = 2, y = 6

(2, 6)

Step-by-step explanation:

The system of equations is solved when we find the "x" and "y" pair that is true for both equations.

We can use elimination, which is when we eliminate one of the variables. This can be done when both equations have a variable that has the same number.

Make both equations have "12y". Multiply each term by the same number.

-7x + 4y =10   }x3 =>   -21x + 12y = 30

-5x + 3y = 8  }x4 =>   -20x + 12y = 32

Subtract the equations from each other to get rid of 12y.

.     -20x + 12y = 32

<u>-     -21x + 12y = 30</u>

.          1x + 0y = 2    0y is nothing and 1x is x.

.                    x = 2    We have solved for x.

Now solve for y.

Use one of the equations:

-5x + 3y = 8    Substitute x for 2

-5(2) + 3y = 8     Simplify

-10 + 3y = 8     Start isolating x. Add 10 to both sides

3y = 18    Divide both sides by 3

y = 6    Solved for y.

The system of equations intersect at (2, 6).
