Solve the system using the substituion method -4x+y=8 x-3y=9

lions [1.4K]

Hi there!

x - 3y = 9
x = 9 + 3y

-4x + y = 8
-4(9+3y) + y = 8
-36 - 12y + y = 8
-36 - 11y = 8
-11y = 44
-y = 4
y = -4

x - 3y = 9
x - 3(-4) = 9
x + 12 = 9
x = 21

So, your answers are y = -4 and x = 21.

Hope this helps!

Given a line with a slope of1/2 and a point(6,5) which lies on that find an equation to represent that line

kondor19780726 [428]

Answer:

The equation of the line is given as 2 y - x = 4.

Step-by-step explanation:

Here, the slope of the given line = 1/2

The point on the line is (x0,y0) = (6,5)

Now, by POINT SLOPE FORMULA:

The equation of line with (x0,y0) and slope m is written as:

(y - y0) = m (x-x0)

So, here the equation of line is given as

$( y- 5) = \frac{1}{2} (x-6)\\\implies 2( y-5) = ( x-6)\\or, 2y - 10 = x - 6\\\implies 2y - x = 4$

Hence the equation of the line is 2 y - x = 4.
