Answer 1

3x+2y=18
8x+6y=50


ill give u elimination sub would be hard


elimination: -3(3x+2y=18)         multiple bye -3 
-9x-6y=-54                           6's cancel leaving -x=-4
8x+6y=50

-x=-4          divide bye -1
--------
-1   -1
(x=4)

3(4)+2y=18       substitute 4 into one of the 2 original equations i picked first
12+2y=18          subtract 12
2y=6        divide by 2
y=3
final answer is points (4,3)
