S must equal 1, because without the variable, 55=55<span />
2(5x+7)+8x-7=27
We move all terms to the left:
2(5x+7)+8x-7-(27)=0
We add all the numbers together, and all the variables
8x+2(5x+7)-34=0
We multiply parentheses
8x+10x+14-34=0
We add all the numbers together, and all the variables
18x-20=0
We move all terms containing x to the left, all other terms to the right
18x=20
x=20/18
x=1+1/9
Step-by-step explanation:
-9 x s = 6
-9 x 6 =s
-54=s
s=-54
C, because 36 is just under half of 80, so it is 9/20.
