What is the solution of the equation 4(X+5)=X+8

1 answer:

5 0

4 ( x + 5 ) = x + 8

4 * x + 4 * 5 = x + 8

4 x + 20 = x + 8

4 x - x = 8 - 20

3 x = -12

x = -12 / 3

x = - 4

hope this helps!

Step-by-step explanation:

Inequality to describe problem:

$- 6 < x < 21$

x represents the unknown integer(s).

Integers are positive or negative numbers that don't have a fraction, or a decimal.

Positive integers that work in the inequality:

$- 6 < 1< 21$

$- 6 < 2 < 21$

$- 6 < 3 < 21$

$- 6 < 4 < 21$

$- 6 < 5 < 21$

$- 6 < 6 < 21$

$- 6 < 7 < 21$

$- 6 < 8 < 21$

$- 6 < 9 < 21$

$- 6 < 10< 21$

$- 6 < 11 < 21$

$- 6 < 12 < 21$

$- 6 < 13 < 21$

$- 6 < 14 < 21$

$- 6 < 15 < 21$

$- 6 < 16 < 21$

$- 6 < 17 < 21$

$- 6 < 18 < 21$

$- 6 < 19 < 21$

$- 6 < 20 < 21$

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 work out as positive integers.

Knowing that

Molodets [167]

Answer:

a. x/y = 2 b) y/x +y =1/3 c) x-y/y= 1 d) y/x = 1/2

Step-by-step explanation:

Solve for

a) x/y

as we know x +y/y = 3

x+y= 3y

x= 3y-y

x= y(3-1)

x/y= 3-1

x/y = 2

b) y/x+y

as we know x +y/y = 3

x+y = 3y

1= 3y/x+y

1/3 = y/x+y

So y/x +y =1/3

C) x-y /y

as we know x +y/y = 3

x +y = 3y

subtracting 2y from both sides

x +y -2y = 3y- 2y

x-y = y

dividing both sides by y

x-y/y = y/y

x-y/y= 1

d) y/x

as we know x +y/y = 3

x +y = 3y

x= 3y- y

x= 2y

dividing both sides by x

x/x = 2y/2x

1 = 2 x (y/x)

1 / 2 = y/x

Or y/x = 1/2

Best of luck.

please mark me brainliest.
