A. Adding 2x to 3x
B. Subtracting 5 from both sides
C. Adding 2x to -2x
D. Dividing by 5 on both sides

A. Adding 2x to 3x

Step-by-step explanation:

3x + 5 - 2x = 10

1x + 5 = 10

x + 5 = 10

Subtract 5 from both sides

x + 5 - 5 = 10-5

x + 0 = 5

x = 5

step-by-step explanation:

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.
