Which step could be used to solve x + 3.6 = -1.7 for x in one step? check all that apply. [ ] add 3.6 to both sides [ ] add -3.6 to both sides [ ] add 1.7 to both sides [ ] add -1.7 to both sides [ ] subtract 3.6 from both sides [ ] subtract 1.7 from both sides

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.)
