On the basis of data from 1990 to 2006, the median income y in year x for men and women is approximated by the equations given below, where xequals0 corresponds to 1990 and y is in constant 2006 dollars. if these equations remain valid in the future, in what year will the median income of men and women be the same?
men: -255x+2y=56,937women: - 842x+3y=42,751

In 2083

Step-by-step explanation:

Given,

The median income y in year x since 1990 for men,

-255x+2y=56,937     .......(1),

For women,

-842x+3y=42,751       ........(2),

From equation (1),

2y = 56937 + 255x

From equation (2),

842x+3y=42,751,

When the median income of men and women are same,

∵ 1990 + 93 = 2083,

Hence, in 2083, the median income of men and women would be the same
