miv72 [106K]

Answer:

(X,Y)(18,12)

Step-by-step explanation:

x + y = 30

2x + 4y = 84

___________

2x+2y=60

2x+4y=84

_________

-2y=-24/-2y

y=12

2x+4(12)=84

2x+48=84

2x=84-48

2x/2=36/2

9 over 3x = 4 over x + 2
Elan Coil [88]

The equation that we have been given is:

\frac{9}{3x}  =  \frac{4}{x+2}

In order to solve for the value of 'x', we'll have to use cross-multiplication.

Cross-multiplication is a method in which the numerator of one fraction is multiplied by the denominator of another fraction that it is equal to.

Let's cross-mutliply the numerators and denominators:

\frac{9}{3x}  =  \frac{4}{x+2}

9*(x+2) = 4*(3x)

Distribute the numbers into the parentheses.

9x + 18 = 12x

Simplify by subtracting both sides by 9x:

9x - 9x + 18 = 12x - 9x

0 + 18 = 3x

18 = 3x

3x = 18

Divide both sides by 3:

\frac{3x}{3} = \frac{18}{3}

<u>x = 6</u>

<u></u>

Let me know if you'd like me to explain anything I did here.
