What value or values of x satisfy 2|x + 5.3| = 4.2?

Mathematics

Furkat [3]3 years ago

Answer:

Step-by-step explanation:

2 | x + 5.3 | = 4.2

| x + 5.3 | = 4.2 / 2

| x + 5.3 | = 2.1

x + 5.3 = 2.1 x + 5.3 = - 2.1

x = 2.1 - 5.3 x = -2.1 - 5.3

x = - 3.2 x = - 7.4

solution is : x = -3.2 or x = -7.4

Solve the system of equations. If a system has one unique solution, write the solution set. Otherwise, determine the number of s
Sauron [17]

The value of x, y and z from the system of equation are -1, -8 and 5 respectively.

Data;

  • -2x + 6y + 3z = -31
  • -3y + 7z = 59
  • 2z = 10

<h3>System of Equation</h3>

To solve this problem, we have to solve the system of equation using substitution method.

From equation (iii)

2z = 10\\z = 5

let us substitute the value of z into equation (ii)

-3y + 7z = 59\\z = 5\\-3y + 7(5) = 59\\-3y + 35 = 59\\-3y = 59 - 35\\-3y = 24\\y = -8

Let's substitute the value of x and y into equation (i)

-2x + 6y + 3z = -31\\y = -8, z = 5\\-2x + 6(-8) + 3(5) = -31\\-2x - 48 + 15 = -31\\-2x - 33 = -31\\-2x = -31 + 33\\-2x = 2\\x = -1

From the calculation above, the value of x, y and z are -1, -8 and 5 respectively.
