Seven adult tickets and eight kids tickets
The answer is 35 so that's it
2 times 2=4
multiply first equation by 2 to get
-4x+6y=12
then add to get
-4x+6y=12
<u>4x-2y=8 +</u>
0x+4y=20
4y=20
y=5
sub back
-2x+3y=6
-2x+3(5)=6
-2x+15=6
-2x=-9
x=9/2=4.5
the number to multiply by is 2
Step-by-step explanation:
2(x3+5x2−2x2y−10xy)
=(2)(x3+5x2+−2x2y+−10xy)
=(2)(x3)+(2)(5x2)+(2)(−2x2y)+(2)(−10xy)
=2x3+10x2−4x2y−20xy
=2x3−4x2y+10x2−20xy
