Answer:
Step-by-step explanation:
Hello,
we assume that a is different from 0 otherwise there is not much we can say on c and then we can write
a(c+b)=d
<=> ac+ab=d
<=> ac = d - ab
<=> 
Hope this helps
If I am reading the equations correctly, they are:
5x - 14 = 3x AND 7x + 12 = x - 6
If this is correct, the first one would be worked out like this:
5x (- 5x) - 14 = 3x (- 5x)
- 14 = - 2x
- 14 (/ - 2) = - 2x (/ - 2)
7 = x
The second would be worked out like this:
7x + 12 (+ 6) = x - 6 (+ 6)
7x + 18 = x
7x (- 7x) + 18 = x (- 7x)
18 = - 6x
18 (/ - 6) = - 6x (/ - 6)
- 3 = x
I hope this is what you are looking for :)
Answer:
x = 1, y = 2
Step-by-step explanation:
x + y = 3 => 2x + 2y = 6
2x + 3y = 7
-)2x + 2y = 6
=> y = 1, x = 2
The 3 numbers could be 0.5, 1.1 and 4.4.
In the list above, there is only 1 number less than 1. It is 0.5.
The other 2 numbers are larger than 1.
If you add up the 3 numbers you will have exactly 6.
0.5 + 1.1 + 4.4 = 6
