Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11

I think you are doing limits so this is what I did
and that's how I factored using the box method because it's easier to track distribution.
We can use a system of equations to solve this.
Length 1 = x
Length 2 = y
Set up the system.
2x+2y=38
x+1=4y
Isolate the variable on one equation.
x=4y-1
Substitute that into the other equation.
2(4y-1)+2y=38
Solve.
8y-2+2y=38
10y=40
y=4
Substitute back into other equation.
x=4(4)-1=16-1=15
The lengths are 15 cm and 4 cm.
Hope this helps!
