You have to distribute the 7 to x and 2 so :
7x+14=2x-1
Add one to both sides (inverse operations)
7x+14=2x-1
+1 +1
7x+15=2x
Cross Cancel by subtracting 7x from both sides
7x+15=2x
-7x -7x
15=-5x
Divide by -5
15/-5= -5/-5
X= -3

P(F) = 0.5
P(L) = 0.3
$P(F\cap L)=0.2$
$P(F\cap L')=0.5-0.2=0.3$
$P(F'\cap L)=0.3-0.2=0.1$
$P(F'\cap L')=1-0.3-0.2-0.1=0.4$
