= Let Martina's cousin's age be = n
= Let her age be = n+12
After four years,
Cousin's age = n+4
Her age = n+12+4=n+16
But according to the question her age = 3(n+4) = 3n+12
Thus,
3n+12=n+16
3n-n=16-12
2n=4
n=4/2
Thus ,
Her cousin's present age = n = 2
Her cousin's present age = n = 2Her present age = n+12 = 2+12=14

Answer:
12
Step-by-step explanation:
5(x-1) +3x = 7(x + 1)
5 × x - 5×1 + 3x = 7 × x + 7 × 1
5x-5+3x=7x+7
8x-5=7x+7
8x-7x=7+5
x=12
