Santiago is eight years younger than Juan is today. If, in four years, Santiago will be half Juan’s age, how old is Santiago tod

kvv77 [185]

Answer:

d) 4.

Step-by-step explanation:

Let Santiago be x years old today.

Then Juan is x + 8 years old.

In 4 years Santiago will be x + 4 years.

In 4 years Juan will be x + 12 years.

From the given information:

x + 4 = 0.5(x + 12)

x = 0.5x + 6 - 4

0.5x = 2

x = 2 / 0.5

x = 4.

3-x=5x+21

vlada-n [284]

Answer:

<h3> $\boxed{ \sf{ \bold{- 3}}}$ </h3>

Step-by-step explanation:

$\sf{3 - x = 5x + 21}$

Move 5x to left hand side and change it's sign

⇒ $\sf{ - x - 5x + 3 = 21}$

Move 3 to right hand side and change it's sign

⇒ $\sf{ - x - 5x = 21 - 3}$

Collect like terms

⇒ $\sf{ - 6x = 21 - 3}$

Subtract 3 from 21

⇒ $\sf{ - 6x = 18}$

Divide both sides of the equation by -6

⇒ $\sf{ \frac{ - 6x}{ - 6} = \frac{18}{-6}}$

Calculate

⇒ $\sf{x = -3}$

Hope I helped!

Best regards!!
