Help please 4(2x-1)+3=8x+1

Mathematics
1 answer:
Gemiola [76]2 years ago
7 0
<h3>hello!</h3>

Use the distributive property:-

4(2x-1)

8x-4

8x-4+3=8x+1

8x-8x-4+3=1

8x-8x-1=1

0-1=1

-1=1

Wait, what? -1 is equal to 1?

Hence, the equation has no solutions.

Hope it helps :)

3x+4y=-23 <br> 2y-x=-19 <br> What is the solution (x,y) to the systems of equations above?
Shkiper50 [21]
If we multiply the bottom equation by 2 and move x to the right, it becomes:

4y = 2x-38

Now we can substitute it for the 4y in the top equation:

3x + (2x-38) = -23 => 5x = -23+38 => 5x = 15 => x=3

Then 4y = 2*3-38 => y = -8

So the solution is (3,-8)
