Answer:

The result for the equation is x = -8 .

Step-by-step explanation:

-Solve the equation:

0.75x -0.5 =x +1.5

-Subtract x from 0.75x :

0.75x -0.5-x =x -x+1.5

-0.25x -0.5 = 1.5

-Add both sides by 0.5 :

-0.25x -0.5 +0.5 =1.5 +0.5

-0.25x = 2

-Divide both sides by 0.25 :

\frac{-0.25x}{-0.25} =\frac{2}{-0.25}

x = -8

So, the answer for the equation is x = -8 .

A man is twice as old as his son. Twelve years ago, the man
GrogVix [38]

Answer:

Son's age = 24 years

Man's age = 48 years

Step-by-step explanation:

Let's take the age of son as x

Man's age = 2x

Twelve years ago,

Son's age= x-12

Man's age= 2x-12

Man is three times as old as his son so,

\frac{2x - 12}{x - 12 } =  \frac{3}{1}

Solving for x,

2x-12(1) = x-12(3)

2x-12 = 3x-36

2x-3x = -36+12

-x = - 24

x = 24

So if we substitute the values we get,

Son's age = 24 years

Man's age = 48 years

Hope you understand :)
