The life expectancy, y, of a person born in Japan is approximated by the equation y = 0.27x + 74, where x is the number of years since 1970. solve for x

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

the 3rd on is correct

step-by-step explanation:

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:
