Answer: 23
Step-by-step explanation:
Benches = x
4x + 3 = 5x - 2
x = 5
this equals that x = 5 because we put the unknown algebraic number on one side and the numerals on the other.
So if there are 5 benches then the number of children will be
4 * 5 + 3 or 5 * 5 - 2, which both equal 23.
Therefore, the answer to this question is 23 children
Hi! Your answer is q = -9
Please see an explanation for a better and clear understanding to your problem.
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
Since we want to solve for q-term. That means we are going to isolate q-term.

We can add 4 and 9 together.

Because we want to know the value of q. That means we have to isolate q-term by subtracting both sides by 13.

We are reaching to the final step where we divide the whole equation by 3.

Finally, the solution for this equation is q = -9. But what if you are not certain or sure about the answer? Let's check it out!
To check the answer, simply substitute q = -9 in the equation.

Notice that the equation is true for q = -9. Hence, we can conclude that the solution for this equation is q = -9.
Hope this helps!
The answer is 8
8*2=16-4=12
That would be 3'000 + 4000 + 400 + 80 = 7,480
