When solving the equation, what property was used to go from step 3 to step 4?
Step 1: -(2x+3= x-18
Step 2: -2x-3=x-18
Step 3: -3=3x-18
Step 4: 15=3x
A)APOE
B)SPOE
C)MPOE
D)DPOE
B- spoe!!!
thank you
To determine which property was used to go from step 3 to step 4 in solving the equation, let's analyze the steps:
Step 1: -(2x+3= x-18
This step seems to have a typo, as there is an extra opening parenthesis without a closing parenthesis.
Step 2: -2x-3=x-18
In this step, we can see that the equation was multiplied by -1 to change the sign of each term.
Step 3: -3=3x-18
In this step, the equation appears to have been simplified by adding 2x to both sides. This results in the x terms getting combined on the right side.
Step 4: 15=3x
The equation has been further simplified by adding 18 to both sides to isolate the 3x term, resulting in the final answer, which is 15=3x.
Based on these steps, the property used to go from step 3 to step 4 is addition property of equality (APOE). Therefore, the correct answer is A) APOE.
