PLS HELP 3x = 10 = 13x?

3x=10+13x

We simplify the equation to the form, which is simple to understand  

3x=10+13x

We move all terms containing x to the left and all other terms to the right.  

+3x-13x=+10

We simplify left and right side of the equation.  

-10x=+10

We divide both sides of the equation by -10 to get x.  

x=-1                     

idk im srry

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.
