Answer:
(-1,3)
Step-by-step explanation:
2x-3y=9 multiply by 3 to get 6x-9y = 27
3x+5y=4 multiply by -2 to get -6x-10y= -8
Add together -19y=19, y= -1
Put y into either equation => 2x-3(-1)=9, 2x+3=9, 2x=6, x=3
Yes, because 3 1/3 times 45 equals 150 which leaves 10 cups left over:
Here is an example:
3(4x +7)
2( 3 +5) =2( 3 ) = 2 ( 5 )
