Find an equivalent system of equations for the following system x + 2y = 2, -4x + 4y = -8

2x + 4y = 4

-8x + 8y = -16.

Step-by-step explanation:

We can find an equivalent system by multiply the 2 equations by 2.

x + 2y = 2  multiplied by 2 is 2x + 4y = 4.

Step-by-step explanation:

Given Equations:

        Equations:1

    Equation:2

Multiplying equation:1 by '2'

        Equation:3

Using Elimination Method, Subtracting Equation:2 from Equation:3

Putting the value of 'x' in Equation:1

The value of 'x' is 2

The value of 'y' is 0

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
