Answer:
9d+7
Step-by-step explanation:
when you subtract you 'add the opposite' so we can rewrite this subtraction problem as an addition problem as follows:
6d + 5 + 2 + 3d
combine 'like' terms to get:
9d + 7

Answer: x = -3/k</h3>
==============================================
Work Shown:
kx+7 = 4
kx+7-7 = 4-7 .... subtract 7 from both sides
kx = -3
kx/k = -3/k .... divide both sides by k
x = -3/k
The value of k cannot be zero. As the steps show, we are following PEMDAS in reverse to undo each operation to help isolate x. Subtraction is the opposite of addition, and division is the opposite of multiplication.
