A. subtract the bottom equation from the top equation
Step-by-step explanation:
The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

2 yards = 6 feet
6 times 5 is 30
30 ft squared
Bagels 6x12=72
apples 8x9=72
cookies 12x6=72
juice 9x8=72
72/4 kids is 18 lunches
So 15-7 is 8
Here are some things I did:
10-2 or 28-20
Place value is the value individual digit has in its location:
in order from higher to lower value, there is thousands, hundreds, tens, and
ones.
When you divide by 10, you are affecting (only once) every digit from its current
place value to the right.
For example 1000 divided by 10 = 100, you have relocated every digit to the
right, making the zero dissolve (or better yet, divided by a hidden and in this
case unusable comma).
