A: 5x − 2y = 10
Nuetrik [128]

Answer:

D) Multiply A by -4 and B by 5

Step-by-step explanation:

5x-2y=10

4x+3y=7

----------------

-4(5x-2y)=-4(10)

5(4x+3y)=5(7)

----------------------

-20x+8y=-40

20x+15y=35

---------------------

23y=-5

y=-5/23

5x-2(-5/23)=10

5x+10/23=10

5x=10-10/23

5x=230/23-10/23

5x=220/23

x=(220/23)/5

x=(220/23)(1/5)

x=220/115

x=44/23

7x-y=19 2x-3y=19 solve by elimination​
avanturin [10]

Answer:

x=2 y=-5

Step-by-step explanation:

7x-y=19

2x-3y=19

Multiply the first equation by -3

-3(7x-y)=19*-3

-21x +3y =-57

Add this to the second equation to eliminate y

-21x +3y =-57

2x-3y=19

-----------------------

-19x = -38

Divide by -19

-19x/-19 = -38/-19

x = 2

Now we need to find y

7x-y = 19

7(2) -y =19

14 -y =19

Subtract 14 from each side

14-14 -y=19-14

-y=5

Multiply by -1

y = -5
