3w +2 =7w
-3w -3w
2=4w
Divide each side by 4
1/2=w

Check your answer:
3 (1/2) + 2 = 7 (1/2)
(3/2) + (4/2) = (7/2)
(7/2) = (7/2)

Hope this helps.

$3w + 2 = 7w$

$3w + 2 = 7w:w$ $|Solve \ for \ w|$

$2=7w-3w$ $|Subtract \ 3w \ from \ both \ sides|$

$
2=4w
 
$

$\dfrac{2}{4}=w$ $|Divide \ both \ sides \ by \ 4|$

$w= \dfrac{1}{2}$

Answer:

(-1/2, 3/4)

Step-by-step explanation:

Let's use the elimination by adding or subtracting method. Note that we have 8y in the first equation, and that we could obtain -8y in the second equation by multiplying the second equation by 2:

2(24x - 4y = -15) => 48x - 8y = -30

Now combine this result (this equation) with the first equation:

2x + 8y = 5

+48x -8y = -30

---------------------

50x = - 25

Dividing both sides by 50, to isolate x, we get

x = -25/50 = -1/2.

Now substitute -1/2 for x in the first equation and solve the resulting equation for y:

2x + 8y = 5

2(-1/2) + 8y = 5, or -1 + 8y = 5, or 8y = 6 (after having added 1 to both sides)

Dividing both sides of 8y = 6 by 8 leads to determining the value of y:

y = 6/8 = 3/4

The solution is (-1/2, 3/4).

y = 19

x = 4(19) + 21(19) = 76 + 399 = 475

3(475) × 7

1425 × 7

Answer:

The sum of money received by Ali, Carrie and Bryan is $ 740.

Step-by-step explanation:

At first we translate mathematically each sentence:

(i) <em>Ali, Carrie and Bryan received a sum of money. </em>

$a$ - Ali's money.

$b$ - Bryan's money.

$c$ - Carrie's money.

(ii) <em>Bryan's money was </em> $\frac{3}{5}$ <em> of Ali's money</em>.

$b = \frac{3}{5}\cdot a$ (1)

(iii) <em>The ratio of Ali's money to Carrie's money was 4 : 1</em>.

$\frac{a}{c} = 4$ (2)

(iv) <em>Ali had $ 160 more than Bryan</em>.

$a = b + 160$ (3)

After some algebraic handling, we have the following system of linear equations:

$3\cdot a - 5 \cdot b = 0$ (1b)

$a - 4\cdot c = 0$ (2b)

$a - b = 160$ (3b)

The solution of the system is: $a = 400$ , $b = 240$ , $c = 100$

The sum of money is:

$s = a + b + c$

$s = 740$

The sum of money received by Ali, Carrie and Bryan is $ 740.
