Answer: 16
Step-by-step explanation:
let a = your present age
a = 2(a+4) - 2(a-4)
a = 2a + 8 - 2a + 8
a = 2a - 2a + 8 + 8
a = 16 yrs is your age
<em>multiply both sides by 5 </em> 3(15k+10)=5(12k-9)
<em>get rid of the brackets</em> 45k+30=60k-45
<em>take away 45k to both sides</em> 30=15k-45
<em>plus 45 to both sides</em> 75=15k
<em>divide both by 15</em> k=5
It is B=24
