Let x or y be 0
4x-2y=5
4(0)-2y=5
-2y=5
Divide -2 and 5 by -2.
y=-2.5
4x-2y=5
4x-2(0)=5
4x=5
Divide 4 and 5 by 4.
x=1.25
I did not check my math, feel free to correct me.

Answer:

$24(f(n))$

Step-by-step explanation:

$f(n+3) = 3^{n+3}\\f(n+1) = 3^{n+1}$

$f(n+3) - f(n+1) = 3^{n+3} - 3^{n+1}$

$= 27(3^n) - 3(3^n)$

$= 24(3^n)$

$= 24(f(n))$

hope this helped! :)

-1(x+2)=2(3x-6) Please solve

Korvikt [17]

$-1(x+2)=2(3x-6)$
$-1(x+2)=2(3x-6)$ distributhing -1 through parantheses
$-1x+(-1)*2=2(3x-6)$
$-x-2=2(3x-6)$ distributhing 2 through parantheses
$-x-2=2*3x-2*6$
$-x-2=6x-2*6$
$-x-2=6x-12$ add x
$-2=6x-12+x$
$-2=7x-12$ add 12
$-2+12=7x$
$10=7x$ divide by 7
$x= \frac{10}{7}$
Answer : x= 1 3/7

An estate of $613,000 is left to three siblings. The eldest receives 2 times as much as the youngest. The middle sibling receive

Assoli18 [71]

Answer:

Eldest: $298500

Middle: $165250

Youngest: $149250

Explanation:

We can show the siblings like this:

e=2y (eldest)

m=16000+y (middle)

To find the value of y, or the youngest sibling, we use an equation.

2y+16000+y+y=613000

Simplify:

4y+16000=613000

Subtract 16000 on both sides:

4y=597000

Divide both sides by 4:

y=149250

The youngest received $149250.

Knowing this, we can plug in the numbers into the original formulas:

e=2(149250)=298500 ...or $298500

m=16000+149250=165250 ...or $165250

y=149250 ...or $149250

Add all those numbers up, and you reach $613000.
