Answer:

Alright, the answer to the equation -52+3= -49

Step-by-step explanation:

I don't know how the heck Marcus and Jeremy got -22 and 28 but both are wrong. If there were a picture so I could see their work, I would be able to figure it out.

Anyways, The math is:

-52 + 3 which is pretty much 52-3 and then the answer has a negative sign.

-52 goes up 3 because technically the negative sign is down. Counting up 3 from 52 equals -49.

What is the solution of 3x + y = 9 and 3x − 5y = 15?
erma4kov [3.2K]

Answer:

Multiply the first equation by five to yield, 15x + 5y = 45. Add this equation to the second equation from the given,

                                      15x + 5y = 45

                            +         3x - 5y = 15

The answer would be 18x = 60. The value of x is 10/3. Therefore, the answer to this item is letter A.
