Answer:

Step-by-step explanation:
We have the expression:

The first thing we want to do, is to have the same denominator in both equations, then we need to multiply the first term by (2/2), so the denominator becomes 4*x
We will get:

Now we can directly add the terms to get:

We can't simplify this anymore
Vertical angles are congruent (equal), and the angles below are vertical angles.
x + 40 = 3x
40 = 3x - x
2x = 40
<u><em>x = 20</em></u>
Answer:
I think it's " 3-10x ..perdón
Answer:
The value of the given expression x-4b is 29
Step-by-step explanation:
We have to evaluate the expression:
Given: b = -6 and x = 5
Substitute these in the given expression we have;

therefore, the value of the given expression when b = -6 and x =5 is 29
