4b + 22 = 5 (b + 4) - 1 (remove the parantheses)
4b + 22 = 5b + 20 - 1 (calculate)
4b + 22 = 5b + 19 (move the terms)
4b - 5b = 19 - 22 (collect like terms and calculate)
-b = -3 (change the signs)
<em>b = 3</em>
Let
be the dimensions of the rectangle. We know the equations for both area and perimeter:


So, we have the following system:

From the second equation, we can deduce

Plug this in the first equation to get

Refactor as

And solve with the usual quadratic formula to get

Both solutions are feasible, because they're both positive.
If we chose the positive solution, we have

If we choose the negative solution, we have

So, we're just swapping the role of
and
. The two dimensions of the rectangle are
and

Answer:
idk if this is right but if it is right can i have brainliest and if it is wrong then rate me a 1 and you can umm... report me if u want
Step-by-step explanation:
Let's solve for x.
6x+7y=13x
Step 1: Add -13x to both sides.
6x+7y+−13x=13x+−13x
−7x+7y=0
Step 2: Add -7y to both sides.
−7x+7y+−7y=0+−7y
−7x=−7y
Step 3: Divide both sides by -7.
−7x
−7
=
−7y
−7
x=y
That sounds correct to me.
