Answer:

• let the number be x

• Mathematical interpretation and manipulation of the above statement:

$\hookrightarrow \: { \tt{13 - 3x = 5 + x}}$

• solve and simplify:

${ \tt{x + 3x = 13 - 5}} \\ \\ { \tt{4x = 8}} \\ \\ \dashrightarrow \: { \boxed{ \rm{ \: x = 2 \: }}}$

Answer: The number is 2

Solve for y. ln(y-1)-ln2=x+ln x

alexandr402 [8]

$ln(y - 1) - ln(2) = x + ln(x)$
$e^{ln(y - 1) - ln(2)} = e^{x + ln(x)}$
$\frac{e^{ln(y - 1)}}{e^{ln(2)}} = e^{x} * e^{ln(x)}$
$\frac{y - 1}{2} = e^{x} * x$
$\frac{1}{2}y - \frac{1}{2} = xe^{x}$
$2(\frac{1}{2}y - \frac{1}{2}) = 2xe^{x}$
$y - 1 = 2xe^{x}$
$y = 2xe^{x} + 1$

❗️HELP ASAP❗️

tangare [24]

I think the answer is G.

I think this because of the fact families (like my elementary teacher used to say)
It’s like about multiplication of fact families so make it where it would have fact families with those numbers as the sums.
I hope this helps! Be safe out there.
