So the problem is asking you to combine equations, in this case the Y factor will cancel out so you will be left with the X factor and the total after you add both of the totals together,
6x-4y=16
5x+4y=6
6x-5x=x
16+6=22
x=22

La distancia entre el barco y la base del acantilado es 291.61 metros.
<h3>
¿Como calcular la distancia?</h3>
Podemos pensar en esta situacion como en un triangulo rectangulo. Uno de los catetos mide 687 metros, que es la altura del acantilado.
Y conocemos el angulo al que ese cateto es adjacente, que mide 23 grados.
La distancia entre la base del acantilado y el barco será el otro cateto del triangulo rectangulo.
Entonces podemos usar la relación:
tan(a) = (cateto opuesto)/(cateto adjacente)
Reemplazando lo que sabemos:
tan(23°) = D/687m
tan(23°)*687m = D = 291.61m
La distancia entre el barco y la base del acantilado es 291.61 metros.

3x/4 - x/3
To simplify this, we need to first find a common denominator, or the Greatest Common Factor (GCF) of the two denominators (4 and 3). The GCF of 3 and 4 is 12.
Now, we have to multiply the numerator AND denominator of each individual term by the same factor such that the denominator equals 12.
So for the first term, 3x/4, we know that 12/4 = 3, therefore we need to multiply the fraction by 3/3, which is equivalent to 1.
3x/4 * 3/3 = 9x/12
Now, let's do the same for the other term x/3. We know that 12/3 = 4, therefore we need to multiply the fraction by 4/4, which is equivalent to 1.
x/3 * 4/4 = 4x/12
Now, lets substitute these equivalent fractions back into the original expression.
3x/4 - x/3 = 9x/12 - 4x/12 = 5x/12
Thus, your answer is #4, or 5x/12
