In order to use the elimination<span> method, you have to create variables that have the same coefficient—then you can eliminate them. Multiply the top </span>equation<span> by 5. Next add the</span>equations<span>, and </span>solve<span> for y. Substitute y = 10 into one of the original </span>equations<span> to find x</span>

2(3 + 9x) - 2x
= 6 + 9x - 2x <----------------mistake right here
= 6 + 7x
Correct:
Expanding by using distributive property
2(3 + 9x) - 2x
= 2* 3 + 2 * 9x - 2x
= 6 + 18x - 2x
= 6 + 16x
Step-by-step explanation:
In the following triangle, a= ? , b= 2cm.
m<B= 105° , m<C = 15° ,m< A =?
Now, we know that sum of the interior angles of the triangle = 180°
m<B+m<C +m< A =180°
105°+15°+m< A=180°
m< A= 180- 120° = 60°





1/7 gallon = 1 batch
<em>[multiply by 7 through]</em>
1 gallon = 7 batches
<em>[multiply by 8/9 through]</em>
8/9 gallon = 7 x 8/9
8/9 gallon = 6 2/9
<em>[Good enough to make 6 batches, not enough to make 7 batches]</em>
So he can make 6 batches of collard green
