If y varies directly with x when y=8,x=20 find the value of x when y=42
Alecsey [184]

The value of x is 105 when y=42

Step-by-step explanation:

A direct proportion means that the change in one quantity will also cause the change in other quantity

Given

y varies directly with x

x ∝ y

when the proportionality symbol is removed a proportionality constant is introduced

x=ky\\k=\frac{x}{y}\\Putting\ y=8\ and\ x=20\\k=\frac{20}{8}\\k = \frac{5}{2}\\So,\ the\ equation\ will\ be\\x=\frac{5}{2}y\\Putting\ y=42\\x=\frac{5}{2}*42\\x=5*21\\x= 105

The value of x is 105 when y=42

Solve using either substitution or elimination<br> X-3Y=-14 <br> X-Y=-2
Paraphin [41]
Answer: (4,6)


Explanation:

x - 3y = -14
x - y = -2

Multiply a -1 to the first equation so the x’s can cancel out.

-x + 3y = 14
x - y = -2

Subtract the two equations together.

2y = 12

y=6

Now, plug in y to one of the original equations.

x - (6) = -2

x=4

Therefore, the answer is: (4,6)
