v=vanilla
c=chocolate
A.
4v+c=45
v+c=27
b.
multiply 2nd equation by -1 and add to first
4v+c=45
-v-c=-27 +
3v+0c=18
3v=18
divide both sides by 3
v=6
sub bac
v+c=27
6+c=27
minus 6
c=21
21chocolate

Answer:
37 and 26
Step-by-step explanation:
Let the bigger number be x and the smaller number be y.
Then the two numbers total 63 will give us:
y+x=63------>eqn1
The two numbers have a difference of 11.
y-x=11------->eqn2
We add equations 1 and 2 to obtain:
2y=74
Divide both sides to get:
y=37
Put y=37 into eqn2 to get:
37-x=11
x=37-11
x=26
This larger number is 37 and the smaller number is 26
