SOLVE USING ELIMINATION *20 POINTS* 1. 3x - y = 28

3x - y = 14

a. (8,-4)

b. (-7,7)

c. (7,-7)

d. (-4,8)

2. x+ 4y 13

2x + 3y 6

a. (3,5)

b. (-3,4)

C. (4,5)

d. (4,4)

3. 12r-9y 30
6x + 15y = 54

A. x = 4 and y 2

B. x = 2 and y = 4

C. x = 14 and y 2

D. x = 37/7 and y =26/7

4. x + 3/2 y = -3

6/7x + 7y = -8

A. (27/8, -1/4)

B. (9/2, -5)

C. (-3/11, -10/11)

D. (-63 / 40, -19/20)

1. No answer ( may be due to incorrect question)

2. x = -3

y = 4

3. x= 4

y = 2

4.x = -63/40

y= -19/20

Step 1

Multiply equation 1 by the coefficient of x in equation 2

Multiply equation 2 by the coefficient of x I'm equation 1

(after completing this step you will derive equation 3 and 4 )

Step 2

Subtract equation 4 from equation 3

Step 3

Divide both sides of the equation by the coefficient of y

Step 4

substitute your value for y in equation 1 or 2

(after this you will derive the values of x)

Note : This method is for the Elimination of x

I hope it helps

step-by-step explanation:

goog be able to you with that maybe

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
