Step-by-step explanation:
2(x−5)
=(2)(x+−5)
=(2)(x)+(2)(−5)
=2x−10
Well u can't get division but division is the opposite of multiplication so if it was 12 divided by 2 it would be 6 because 6 times 2 is 12
Answer:
All real numbers except 6
For the given systems A and B:
1) Replace the first equation of A by the sum between the two equations of A.
2) Yes, the systems are equivalent.
<h3>
How to get system B from system A?</h3>
Here we have the two systems of equations:
A:
6x - 5y = 1
-2x + 2y = -1
B:
4x - 3y = 0
-2x + 2y = -1
The second equation is the same in both systems, so we only look at the first equations.
In A we have:
6x - 5y = 1
If we add the second equation of A, then we get:
(6x - 5y) + (-2x + 2y) = 1 + (-1)
4x - 3y = 0
This is the first equation of B.
Then we need to replace the first equation by the sum between the first and second equations.
2) Are the systems equivalent?
Yes, because we did not "modify" system A, we just rewrite it and we got system B, then both systems have the same solutions.
