Alvin’s first step in solving the given system of equations is to multiply the first equation by 2 and the second equation by –3. Which linear combination of Alvin’s system of equations reveals the number of solutions to the system?
9x + 4y = 36
6x + 2.5y = 24

Answer 1

its C

Explanation:

Answer 2

After multiplying by the given coefficients and adding, the new equation obtained is:
8y - 7.5y = 0

after doing the calculations the answer is:
y = 0
x = 4

Because the two equations formed were independent, they had one solution
