What is the value of x? Enter your answer in the box.

x= 20

Step-by-step explanation:

We can use ratios to solve

11                 10

=

11+121          10 + 5x+10

Simplify

11                 10

=

132          5x+20

Using cross products

11 * (5x+20) = 10 *132

Divide each side by 11

11/11 * (5x+20) = 10 *132/11

5x+20 = 10*12

5x+20 = 120

Subtract 20 from each side

5x = 100

Divide by 5

5x/5 =100/5

x = 20
