Explanation:

(1) The given equation is :

2(x + 3)=5x + 6 - 3x

Solving LHS first.

2(x + 3) = 2x +6

Solving RHS

5x + 6 - 3x  = 2x+6

LHS = RHS

So, it is always true.

(2) The given equation is :

x - 3=2x - 3 - x

LHS = x - 3

Solving RHS

2x - 3 - x = x-3

LHS = RHS

So, it is always true.

the answer is 0.42 is that is an option. this question provides no info
