Answer:
answer is 5
Step-by-step explanation:
I used a calculator
If we call the number x, we can write an equation:
x + 12 = 3x - 32
and now we can solve
- x
12 = 2x - 32
+ 32
44 = 2x
÷ 2
22 = x
So your answer is 22, I hope this helps!
P (perimeter)= (5x-7) + (3x-4) + (2x-6)
P= (5x+3x+2x) + (-7-4-6)
P= 10x-17
