First you want to get rid of the bracket on the right which gives you:
11x-0.07=10x-3.1
Next you get both terms with x and both terms without x on the same sides respectively, so add .07 on both sides and take away 10x gives you
(1) x = - 3.03

Distribute the 10 on the right side of the equation.
11x-0.07=10x-3.1
Subtract 10x from both sides and add 0.07 to both sides.
x = 3.17

11x - 0.07 = 10(x - 0.31)
11x - 0.07 = 10x - 3.1
x = - 3.03
Answer: x = - 3.03
Proof:
11(- 3.03) - 0.07 = 10(- 3.03 - 0.31)
- 33.33 - 0.07 = - 30.3 - 3.1
- 33.4 = - 33.4

11x-.07=10(x-.31) use distributive property
11x-.07=10x-3.1
+.07 +.07
11x=10x-3.03
-10x -10x
x=3.03
