Solve for the value of x.

x = 3

Step-by-step explanation:

x + x + x could also be written as 3x, and count the number of "1's" given on both sides:

3x + 4 = 13

=> subtract 4 on both sides of "="

3x = 9

=> Divide by 3 on both sides of "="

x = 3

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
