Your brother is 15 your age. Your sister is 7 years older than your brother. Your sister is 11 years old. Write and solve an equation to find your age a.

Sagot :

Answer:

  • a = 19
  • a = 15 + b

Step-by-step explanation:

Given:

  • a = b + 15 (a = my age; b = my brother's age)
  • s = b + 7 (a = my age; s = my sister's age)
  • s = 11 (s = my sister's age)

s = b + 7

=> 11 = b + 7

=> b = 4

a = 15 + b

=> a = 15 + 4

=> a = 19

Therefore, the equation is 'a = 15 + 4' and the answer is 'a = 19'.

Hoped this helped.

I apologize if this was incorrect or un-helpful.
  • My age be x
  • Brothers age is y+15
  • Sister's age be z

So

  • z=y+7

As z=11

[tex]\\ \rm\Rrightarrow y+7=11[/tex]

[tex]\\ \rm\Rrightarrow y=4[/tex]

My age=

  • x=y+15
  • x=4+15=19years
