Question

A system of two equations is shown below. What will you need to multiply the
top equation by in order to solve this system using the elimination method?
2x+y = 11
5x + 3y = 29
O A. -3
O B. 5
O c. 2
O D. 2

Answer 1

In order to solve this equation you must eliminate one of the variables.

By multiplying by -3 you eliminate the y variable, making A the correct answer.
-6x-3y=-66
5x+3y=29
-x=-37
x=37
