Answer:
what is the question?
Step-by-step explanation:
What is the value of D? In order to solve, you need to find all the variable values to solve for x.
Start by getting all terms with x on one side and all terms without on the other.
6x+7=8x-15
subtract 6x from both sides
7=2x-15
add 15 to both sides
22=2x
divide both sides by 2
11=x
