Question

7. Find the solution by elimination method: 4x-3y=5 and 7x-15y= ( -1)

​

Answer 1

Answer:

x = 2 , y = 1

Step-by-step explanation:

Answer 2

Step-by-step explanation:

4x - 3y = 5. 1 equation

7x - 15y = (-1) 2 equation

Using elimination methods

multiply equation 1 by 5

20x - 15y = 25

7x. -15y. = -1

- + + sign change

13x. = 26

x. = 26/13

x. =2

put the x value in equation 1

4(2) -3y = 5

8 -3y. = 5

-3y. = 5-8

y. = -3
