9 chairs because 2 to 4 is equal to 1/2 and half of 18 chairs is 9
Answer:
Add 4 on both sides.
In the equation there is a -4.
If -4+4=0, that is how you would get rid of the -4.
But, you need to add 4 to 29 to really get rid of the -4.
So, 29+4 is 33.
b=33
I got -3.........................
-7 - 7p = 3p + 23
Move the -7p over to the right....by adding
-7 = 10p +23
Move the 23 over to the left by subtracting
-30 = 10p
divide by 10
p = -3
1/2=3/6
3/6+1/6=4/6 goodluck
