How do I solve this linear system using the elimination method?

kipiarov [429]

Answer:

Solution: $x=4$ , $y = \frac{5}{2}$

Step-by-step explanation:

<u>System of Equations</u>

Solve the system:

x + 4y = 14

3x - 2y = 7

using the elimintation method.

To use the elimination method, we must add or subtract both equations in such a way that one of the variables goes away, and only one remains.

It requires to multiply one of them by a specific factor to match the coefficients. For example, multiply the first equation by -3:

-3x - 12y = -42

And add it to the second:

3x - 2y = 7

To result:

-14y = -35

Divide by -14:

$y = -35/(-14)$

Simplifying:

$y = \frac{5}{2}$

Now calculate x:

$x = 14 - 4*\frac{5}{2}$

$x = 14-10$

$x=4$

Solution: $x=4$ , $y = \frac{5}{2}$

Use the product of powers property to simplify the numeric expression.

motikmotik

Answer:

The value of $4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}$ is $4^{\dfrac{8}{15}}$ .

Step-by-step explanation:

We need to simplify the numeric expression using property. The expression is as follows :

$4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}$

The property to be used is : $x^a{\cdot} x^b=x^{a+b}$

This property is valid if the base is same. Here, base is x.

In this given problem, x = 4, a = 1/3 and b = 1/5

So,

$4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}}=4^{\dfrac{1}{3}+\dfrac{1}{5}}\\\\=4^{\dfrac{5+3}{15}}\\\\=4^{\dfrac{8}{15}}$

So, the value of $4^{\dfrac{1}{3}} {\cdot} 4^{\dfrac{1}{5}$ is $4^{\dfrac{8}{15}}$ .

Answer:

24x

Step-by-step explanation:

The product of 24 and a number means that 24 is multiplied by some number. When we use the term "some number" in math, we often use "x" as a representation of that number.
