The Brainliest Answer!

'x' be the age of Carol's brother at present

-------------------------------------

-Carol is 5 times as old as her brother

y = 5x -----equation 1

------------------------------------

-She will be 3 times as old as her brother in two years

y + 2 = 3(x+2)

y + 2 = 3x + 6

y -3x = 6 - 2

y - 3x = 4 ----equation 2

----------------------------------

Substitute equation 1 to equation 2

y - 3x = 4

5x - 3x = 4

2x = 4

--------------------------------

Substitute x=2 to equation 1

y = 5x

y = 5(2)
