What is the solution to this system of equations? 2x+y-5z=4 x+3y+z=5 3x-y-4z=-11
GREYUIT [131]

For the given linear system equations, the value for the variables are: x=-2, y=4, and z=-5 - Option C.

System of Linear Equations

System of linear equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point at which the lines intersect.

The question gives:

2x+y-5z=4 (1)

x+3y+z=5  (2)

3x-y-4z=-11 (3)

First, you should sum equations 1 and 2. The results will be:

3x+4y-4z=9 then you have a new equation (4).

3x-y-4z=-11 (3)

3x+4y-4z= 9(4)

Now, you should multiply equation (3) by -1, then you will have:

-3x+y+4z=+11 (3)

3x+4y-4z=9 (4)

After that, you should sum the previous equations: (3) and (4).

5y=20

y=4

For find z, you should multiply equation 2 by -2. After that, you should sum equations 1 and 2.

2x+y-5z=4 (1)

-2x-6y-2z=-10  (2)

Thus, you will have:

-5y-7z=-6, like y=4 you have

-5*4-7z=-6

-20-7z=-6

-7z=14

z=-2

If z=-2 and y=4 from equation 2, you can find x.

x+3y+z=5

x+3*4-2=5

x+12-2=5

x+10=5

x=5-10

x=-5

Ashin has been working in UAE for a decade and saved AED 125,500 which he wants to transfer now to his parent's account in India
saul85 [17]

Answer:

2510000 INR

Step-by-step explanation:

Given

Savings = AED 125500

1\ AED =20\ INR

Required

The amount that will be withdrawn in India

We have:

1\ AED =20\ INR

Multiply both sides by the savings

125500 * 1\ AED =20\ INR * 125500

125500\ AED =125500 * 20\ INR

So, we have:

125500\ AED =2510000\ INR

<em>Hence, the amount that will b withdrawn is: 2510000 INR </em>
