Step one- distribute
6y-9=27
Step 2- subtract 9 on both sides
6y=18
Step 3 divide on both sides
Y=3
7 because 7 • 7 = 49 • 7 = 343
Answer:
m-9
Step-by-step explanation:
m represents how much cards he used to have he gave away 9 so u subtract
Here we have a system of equation like this:

from the first equation we get:

Substitute in the second equation we get:

Substitute i the first equation again we get:

We deduce that:

A is bigger than B.
Answer:
1) A
2) A
3) B
4) D
5)A
6) D
7) A
8) C
9) D
Step-by-step explanation:
1) -5 (-2) -6= 4
2) 3 coins plus c coins = 3 + c
3) x-2 =16, x = 18
4)
=-5. Clearing, z = 60
5) x =13,4
6) 14=t-4. Clearing t = 58
7) -30=j+50, clearing j=80
8) 2.8x=-9.24, clearing x=-3-3
9) 5.8=
. Clearing z=12.76
