Match each system to the number the first equation can be multiplied by to eliminate the x-terms when adding to the second equation.
- 8x +10y = 16
2
- 4x - 5y = 13
10x - 4y = -8
-5x +6y = 10
1/2
3x - y = 1
6x + 5y = 12
-2
- 2x + 6y = 3
4x + 3y = 9
-1/2

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
