Beau has decided to use the method of elimination to solve the system of equations as shown below.
emmainna [20.7K]

Answer:

Step-by-step explanation:

The given equations are:

2x+3y=15                     (1)

and x-3y=3                 (2)

Now, simply adding equation (1) and equation (2), we get

2x+3y+x-3y=15+3

3x=18

x=6

Now, substituting the value of x=6 in equation (2). we get

6-3y=3

6-3=3y

3=3y

y=1

Thus, the values of x and y are 6 and 1 respectively.

In order to solve the system of solution, beau can see that in both  the given equations, coefficient of y is same and is with opposite sign, thus simply adding both the equations will eliminate y and she will get the value of x and then substituting the value of x in any of the equations, she can get the value of y. With this, she can get closer to the solution.

Write an equation of a line in point-slope, slope-intercept, and standard form that has
Inga [223]

Answer:

(a) y + 4x - 14 = 0

(b) y = -4x + 14

(c) y + 4x = 14

Step-by-step explanation:

The formula for calculating the equation of line in point - slope form is given as :

y-y_{1}  = m(x-x_{1} )

where m is the slope

Given from the question :

m = - 4

x_{1} = 2

y_{1} = 6

Substituting into the formula , we have :

y - 6 = - 4(x - 2)

y - 6 = -4x + 8

y + 4x - 6 - 8 = 0

y + 4x - 14 = 0

Therefore :

(a) the equation of the line in point - slope form is y + 4x - 14 = 0

(b) to write it in slope - intercept form , we will make y the subject of the formula , which will give : y = -4x + 14

(c) the equation of line in standard form is ; y + 4x = 14

Solve. Check your solution.<br> -4+s= -68
Andrews [41]
-64 + -4 = -68

That is because 64 + 4 = 68 and the negatives in this case are the same way as if it was all positive.
