Answer:
0.6
Step-by-step explanation:
2/5 divided by 2/3
use reciprocal method
and make it 2/5*3/2
6/10
Answer is x=13/46.
Simply the equation first, 31-1=92x+4 becomes 30=92x+4.
Flip the equation, 30=92x+4 becomes 92x+4=30.
Subtract 4 from both sides, 92x+4-4=30-4, it then becomes 92x=26.
After that, divide both side since x should be left alone, 92x/92=x , 26/92 - divide it by 2 for a smaller number, and finally it becomes 13/46. And finally x=13/46
-8x+3y=28
4x-y=-12
<u><em>Step-by-step explanation:</em></u>
Let's find x and y from matrices and then check for this systems.
Simplify, so we got
7-9
28-24
------
So x=-2
y=4
So we need to put those values and check system.
Hello, there!
4 * x = 4x
4 * 5 = 20
Now, we have 3 + 4x + 20 = 31
Now, let's combine like terms.
3 and 20 are like terms.
3 + 20 = 23
Now, we have 4x + 23 = 31
Now, let's isolate the x.
4x + 23 = 31
-23 -23
4x = 8
FInally, we will simplify this.
4x = 8
--- ----
4 4
x = 2
Our final answer is x = 2
I hope I helped!
