Answer 1

x=20

Explanation:

11/10=121/5x+10

11(5x+10)=1210

5x+10=110

5x=100

x=20

Answer 2

x= 20

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
