Answer: Option (2) and (5) are the correct options.
Step-by-step explanation:
Since, the given expression, x+3.6= -1.7
If we add -3.6 in both sides then we get x+3.6+(-3.6)=1.7-3.6⇒x= -1.9
while,
If we subtract 3.6 from both sides then we get x+3.6-3.6=1.7-3.6⇒x= -1.9
Thus, In the above by adding -3.6 and by subtracting 3.6 we get the value of x in one step.(because after this only x remains in LHS of the given expression)
Therefore, Option (2) and (5) are correct.
Note: Except these two options we can not get x in one step. (we can not get single x in LHS of the given expression by the other options.)
