Let David's current age be ( x ). According to the problem, in 6 years, his age will be ( x + 6 ), and 7 years ago, his age was ( x - 7 ). The equation can be set up as ( x + 6 = 2(x - 7) ). Solving this gives ( x + 6 = 2x - 14 ), leading to ( x = 20 ). Therefore, David is currently 20 years old.

she will be 20 years old
^^^ I have to write a Algebraic Statement
John is 12, and Tim is eight. Four years ago they would've been eight and four.
Let Orgo's current age be ( x ). In 2 years, his age will be ( x + 2 ). Five years ago, he was ( x - 5 ). According to the problem, in 2 years, he will be twice as old as he was 5 years ago: [ x + 2 = 2(x - 5) ] Solving this equation: [ x + 2 = 2x - 10 ] [ 12 = x ] Therefore, Orgo is currently 12 years old.

You are currently 8 years old. Since your mum was 27 when you were born, she is now 27 + 8 = 35 years old. In 5 years, you will be 8 + 5 = 13 years old. Eight years ago, she was twice your age then, which confirms that your current age is indeed 8.

Johnny is 8.Three years ago he was 5.In two years he will be 1010 is twice 5.
the iron age happened about 2.5 million years ago. the iron age was followed by the stone age, which happened about 3 million years ago
5,000 years ago.
6 years ago, they were 26 and 52.Now they're 32 and 58.
