Question

Two times Antonio’s age plus three times Sarah’s age equals 34. Sarah’s age is also five times Antonios age. How old is Sarah?

Answer 1

Answer:

Sarah is 10 years old

Step-by-step explanation:

  2A + 3S = 34                      (S = 5A) x -3      -3S = -15A     -3S + 15A =0      

+ 15A - 3S =0        Add both equations together

17A = 34

A = 2       Plug 2 in for A in the first equation

2(2) + 3S = 34

4 + 3S = 34

-4            -4

3S = 30

S = 10              If this answer is correct, please make me Brainliest!
