andre’s father is 8 years more than twice andre’s age, a. the sum of their ages is 53. how old is andre?

Answer 1

Andre's Father, we'll represent him with F, is twice Andre's age plus eight years. This can be represented by the equation:

F = 2A + 8

where A is Andre's Age.

The sum of their ages is 53, represented by our second equation:

A + F = 53

If you switch the second equation around to A = 53 - F...

you can plug that in for A in the first equation we wrote:

F = 2(53 - F) + 8

F = 106 - 2F + 8

F = 114 - 2F

3F = 114

F = 38
