Answer:
x=3, y=1. (3, 1).
Step-by-step explanation:
x+3y=6
4x-6y=6
------------
simplify 4x-6y=6 into 2x-3y=3
------------------------
x+3y=6
2x-3y=3
--------------
3x=9
x=9/3
x=3
3+3y=6
3y=6-3
3y=3
y=3/3
y=1
Answer:
Answer:
2x^4(10x+9)
Step-by-step explanation:
20x5+18x4
20x5+18x4
=2x4(10x+9)
2x^4(10x+9)
