Step-by-step explanation:
14/20 is 70% he gave away, so 30% is left.
3x+4y=12
9x-2y=15
we will use elimination
multiply 3x+4y=12 by -3
-9x-12y=-36
9x-2y=15
_________ add
-14y=-21
÷-14 both sides
y=1.5
find x
3x+4 (1.5)=12
3x+6=12
-6 both sides
3x=6
÷3 both sides
x=2
x=2
y=1.5
440 x 10 = 4,400. Yes 4,400 is 10 times as much as 440
