Question

HELP ME PLEASEEEE! Thank you

Answer 1

A. Yes

B. Yes

C. No

Explanation:

We can substitute each value in to the equation and see if the sides match up. Let's start with a.

`4\cdot(2)-3 = -2\cdot(2)+9\\8-3 = -4+9\\5 = 5`

So, n = 2 works for equation a. Let's try B.

`9\cdot((10)/(3)) - 19 = 3\cdot((10)/(3)) + 1\\\\\\(90)/(3) -19 = (30)/(3) + 1 \\ 30 - 19 = 10 + 1\\11 = 11`

So, m =
`(10)/(3)` works for B. Now let's try C.

`3(30+8) = 2\cdot(30)-6\\3(38) = 60-6\\114 \\eq 54`

So y = 30 doesn't work for C.

Hope this helped!
