The lnl is an absolute number which basically means it's positive regardless
So now its 7n-7=14
Simply add the 7 to the 14 to get it off the 7n side so you can simplify
Now it's 7n=21
Now just divide
21/7=3
3=N
That means 7 times N=21

"Bert has half as much money as Ernie. If Ernie loses $225 and Bert earns $675, Bert will have twice as much money as Ernie. How
Rzqust [24]

Answer: Ernie has $750 and Bert has \dfrac{750}{2}=\$375

Step-by-step explanation:

Let the amount that Ernie has be 'x'.

Let the amount that Bert has be \dfrac{x}{2}

Amount lost by Ernie = $225

Amount gained by Bert = $675

According to question, we get that

2(x-225)=\dfrac{x}{2}+675\\\\2x-450=\dfrac{x}{2}+675\\\\2x-\dfrac{x}{2}=675+450\\\\\dfrac{4x-x}{2}=1125\\\\\dfrac{3x}{2}=1125\\\\x=\dfrac{1125\times 2}{3}\\\\x=\$750

Hence, Ernie has $750 and Bert has \dfrac{750}{2}=\$375
