Q:
# 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

Accepted Solution

A:

Answer: Option (2) and (5) are the correct options.Step-by-step explanation:Since, the given expression, x+3.6= -1.7If we add -3.6 in both sides then we get x+3.6+(-3.6)=1.7-3.6βx= -1.9while, If we subtract 3.6 from both sides then we get x+3.6-3.6=1.7-3.6βx= -1.9Thus, 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.)
