7x + 8y = 4<br> 3x + 2y = 6
inysia [295]

Answer:

x=4

y=-3

Step-by-step explanation:

use substitution method :

1)

7x + 8y = 4 ... (1)

3x + 2y = 6 ... (2)

2) Create the third equation by using

equation (2)

3x + 2y = 6

3x = 6-2y

x = 6-2y/3 ..... (3)

3) Substitute (3) into (1)

7(6-2y)/3 + 8y = 4

4) Solve the equation

42 - 14y /3 + 8y = 4

42 -14y+24y = 12

10y = 12-42

y = -3

5) Find value of x

x = 6-2y/3

= 6 -2(-3)/3

= 12/3

= 4

If it is possible to label each element of an infinite set S with a finite string of keyboard characters, from a finite list cha
adelina 88 [10]

Answer:

D. We can label the rational numbers with strings from the set (1, 2, 3, 4, 5, 6, 7, 8, 9, / -) by writing down the string that represents that rational number in its simplest form. As the labels are unique, it follows that the set of rational numbers is countable.

Step-by-step explanation:

The label numbers are rational if they are integers. The whole number subset is rational which is written by the string. The sets of numbers are represented in its simplest forms. The rational numbers then forms numbers sets which are countable.
