Answer:The answer is 183, hope I helped.
You can use Substitution to solve this problem:
4x-y=20
-y=-4x+20
y=4x-20
Now you have two equations, and you use the first one to substitute into the second one.
y=4x-20 and -2x-2y=10
-2x-2(4x-20)=10
-2x-8x+40=10
-10x+40=10
-10x=-30
-x=-3
x=3
Now that we have figured out what x is, we can substitute x in to one of the equations to figure out y.
4x-y=20 x=3
4(3)-y=20
12-y=20
-y=8
y=-8
<em><u>So your answer would be x=3 and y=-8</u></em>
The next Numbers in the pattern is 40,41
Because they react to iron and from rust

Answer:
-5
Step-by-step explanation:
Here is how you solve this problem:
First, you set it up like this: 2x+1-3x+2
Second:You are finding f(4) and g(4) so you just plug in 4 for both problems:
2(4)+1-3(4)-2= 9-14= -5
