Bryson’s dad is 38 years old. If this is four years less than three times Bryson’s age, how old is Bryson?

klemol [59]

Answer:

Bryson’s age is 14 years

Step-by-step explanation:

Let

x ----> Bryson’s age

we know that

Bryson’s age multiplied by 3 minus 4 must be equal to 38

The linear equation that represent this situation is

$3x-4=38$

solve for x

Adds 4 both sides

$3x=38+4$

$3x=42$

Divide by 3 both sides

$x=14$

therefore

Bryson’s age is 14 years
