Answer:
C) 5x=5
Step-by-step explanation:
Multiplying an equation by a number means multiplying all its terms by that number.
Multiplying equation one by 2,
2(2x+y=3)
4x+2y=6
Adding that to equation 2,
4x+2y=6
+ x-2y=-1
The result is 5x=5
You can tell if they're similar if they:
1) Have two of the same angles
2) If two pairs of corresponding angles in a pair of triangles are congruent.
3) If they are the same shape
X=36
you add 126 to 162 making it 288, then you minus 5 out of 13 making it 8. 288/8 =36
