<span>2d= a-b/b-c solve for a
Okie, you mean: 2d=a-b:(b-c)
If that, we have a= 2d+b:(b-c)
Done!</span>
Answer:
it looks great! i'd give you an a+
honestly I couldn't make that
We will see that the equation has only one solution, so the correct option is B.
<h3>
How many solutions an equation has?</h3>
For an equation of the form:
p(x) = C
Where p(x) is an expression that depends on x, and C is a constant.
The solutions are all the values of x that make the equality true.
For our case, we have:
x = -5
Notice that there is only one value of x that makes the equality true, if we replace x by -5 we get:
-5 = -5
So that is the only solution for the equation, then we conclude that the equation has only one solution, and the correct option is B.
