Question

6

Identify a possible first step using the elimination method to solve the system and then find the solution to the
system
3x + 2y = 24
6x + 2y = 30
A)
Multiply second equation by 2, solution (2,9).
B)
Multiply first equation by -2, solution (2,9).
Multiply second equation by 2, solution (2, -9).
D)
Multiply first equation by -2, solution (2, -9). Li

Answer 1

B

Explanation:

3x + 2y = 24

6x + 2y = 30

Multiply the first equation by -2.

-6x - 4y = -48

Add to the second

-2y = -18

y = 9

Plug back in the first.

3x + 2(9) = 24

3x = 6

x = 2
