The correct answer is
.05
there are two pieces, both divided in 10 equal segments.
so each piece is 10/10, or namely 1 whole.
two pieces, 10/10 each, is 20/10 for the whole thing, but there are only 11 shaded, so if we take 20 to be the 100%, what is 11 off of it in percentage?

Simplifying
7x + -14 = 4x + 19
Reorder the terms:
-14 + 7x = 4x + 19
Reorder the terms:
-14 + 7x = 19 + 4x
Solving
-14 + 7x = 19 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
-14 + 7x + -4x = 19 + 4x + -4x
Combine like terms: 7x + -4x = 3x
-14 + 3x = 19 + 4x + -4x
Combine like terms: 4x + -4x = 0
-14 + 3x = 19 + 0
-14 + 3x = 19
Add '14' to each side of the equation.
-14 + 14 + 3x = 19 + 14
Combine like terms: -14 + 14 = 0
0 + 3x = 19 + 14
3x = 19 + 14
Combine like terms: 19 + 14 = 33
3x = 33
Divide each side by '3'.
x = 11
Simplifying
x = 11
Hopefully this helps sorry if its confusing
