Question 255164
let s = number of women members of parliament in sweden.
let n = number of women members of parliament in norway.


s + n = 206


2s + 3n = 477


solve for s in the first equation to get s = 206 - n


substitute in the second equation to get 2*(206-n) + 3n = 477


simplify to get 412 - 2n + 3n = 477


combine like terms to get 412 + n = 477


subtract 412 from both sides of equation to get n = 477 - 412 = 65


if n = 65, then s = 206 - 65 = 141


equation of s + n = 206 becomes 141 + 65 = 206 which is true.


equation of 2s + 3n = 477 becomes 2*141 + 3*65 = 477 becomes 282 = 195 = 477 which is also true.


numbers look good.


s = 141 = number of women members of parliament in sweden.
n = 65 = number of women members of parliament in norway.


total members of parliament in sweden is 349.
total women members of parliament in sweden is 141.
141/349 = .404011461 = 40% to the nearest whole percent.


total members of parliament in norway is 165.
total women members of parliament in norway is 65.
65/165 = .393939394 = 39% to the nearest whole percent.
