What is the solution to the system of equations?

Mathematics
1 answer:
Leno4ka [110]4 years ago

Answer:

x = 16 and y = -6

Step-by-step explanation:

x + y = 10

x + 2y = 4

Multiply the first equation by -1 on both sides. Rewrite below it the second original equation.

-x - y = -10

x + 2y = 4

Add the two equations above.

      y = -6

Now we solve for x. Multiply the first original equation by -2 on both sides and write the second original equation below it.

-2x - 2y = -20

  x + 2y = 4

Add the two equations above.

-x = -16

Divide both sides by -1.

x = 16

Solution: x = 16 and y = -6

Write the equation of the line in fully simplified slope-intercept form.
hoa [83]

Answer:

y = -x+3

Step-by-step explanation:

Slope intercept form =>  y = mx+b

To find 'm', the slope, pick 2 coordinates.

(0,3)

(2,1)

Use this equation to find the slope using these 2 coordinates: (y1 - y2)/(x1 - x2)

(3 - 1)/(0 - 2) = -1

m = slope = -1

'b' is the y-intersept, or the point when a line passes through the y-axis. That's (0,3).

b = y-intercept = 3

<em>So the equation will be y = -1x + 3, or y = -x + 3</em>
