There are a total of 204 males and 348 females in the town. Let x represent the number of left-handed females, and let y represent the number of right-handed males. Write a system of equations to represent the situation. What is the value of x, the number of left-handed females? A. 6 B.24 C. 96 D. 108

Answer 1

24

Explanation:

i got it right

Answer 2

Answer: 24

Expenation:

Left handed females = x

right handed females = 348 - x

right handed males = y

left handed males = 204 - y

204 - y = 4x

348 - x = 3y

4x + y = 204 . . . . . . . (1)

x + 3y = 348 . . . . . . . (2)

From (2), x = 348 - 3y

subsituting for x in (1), we have

4(348 - 3y) + y = 204

1392 - 12y + y = 204

12y - y = 1392 - 204

11y = 1188

y = 1188/11 = 108

x = 348 - 3y = 348 - 3(108) = 348 - 324 = 24
