Answer:
3/2 =x
Step-by-step explanation:
These two angles are interior angles. They add up to 180 degrees
20x+5 = 24x-1
Subtract 20x from each side
20x-20x+5 = 24x-20x-1
5 = 4x-1
Add 1 to each side
5+1 =4x-1+1
6 =4x
Divide by 4
6/4 = 4x/4
3/2 =x

5) Working alone, Juan can harvest a field in 13 hours. Shayna can harvest the same field in 14 hours. Find how long it would take them if they worked together.
Subtract 10x
10x + y = -19
10x + 3y = -17
You would get:
-2y = -2
Two negatives make a positive number! Divide
y = 1
Plug in
10x + (1) = -19
10x = -20
Divide
x = -2
Your solutions are
x = -2
y = 1
