I don't really speak Spanish but I'll guess that says
How do I solve y = 1 - 2.5
Unless I'm missing something, there's not even any algebra here.
The way we subtract a bigger number from a smaller number is first we subtract the smaller number from the bigger number the regular way, then we prepend a minus sign.
y = 1 - 2.5 = -(2.5 - 1) = -1.5
Let us take each number as x = 2x , 3x, 4x
(2x)³+(3x)³+(4x)³=12375
8x³+27x³+64x³=12375
99x³=12375
x³=12375/99
=125
x =∛125
x=5
2x=2×5=10
3x=3×5=15
4x=4×5=20
therefore, the three numbers are 10,15 and 20 .....
Hope it helps !!
The numbers are: 2n and (2n+2)
we can suggest this equation:
4(2n)=2(2n+2)-12
We compute this equation:
8n=4n+4-12
8n-4n=-8
4n=-8
n=-8/4
n=-2
we compute the numbers:
2n=2(-2)=-4
2n+2=-4+2=-2
answer: the numbers are -4 and -2.
