Answer 2

Step-by-step explanation:

X+X+8+2X=20

as we know that addition is commute so we can shift no on the same side with their sign (+ or -) attached

so above question can be written as

X+X+2X+8=20

now combine like terms

4X+8=20

now we can transfer 8 from LHS to RHS with opposite sign

4X=20-8

=>

4X=12

$\huge \boxed{x = 3}$

so the answer is 3
