Answer:
423
Step-by-step explanation:
Start by setting up a formula.
x = the shorter piece
total = 1313
longer piece = (x*2) + 44
x + (x*2) + 44 = 1313
Simplify
3x + 44 = 1313
Now we must solve for x.
Whatever you do on the left side of the equal sign must also be done on the right.
The goal is to get x by itself on the left side.
Do the easiest thing first, which is usually addition or subtraction. In this case, subtract 44 from both sides.
3x + 44 - 44 = 1313 - 44
3x = 1269
Now the only way to cancel out the 3 on the left is to divide by 3. Since 3/3 =1. Remember this must be done on both sides to keep things equal.
3x/3 = 1269/3
x=423
