8 years

Step-by-step explanation:

We can use the equal values equation to put your equation into this; 1x + 5=1.25 + 3

(? I turned the inches into feet) then silve from there

x + 5 = 1.25x + 3

subtract x

5 = 0.25x + 3

subtract 3

2=0.25x

multiply by 4

8=x

In 8 years they will both be 13 feet tall
