**Weegy:** 3s + 5t = 60 ......(1)
2s + 3t = 39 ......(2)
(1)*2 - (2)*3: t = 3, s = (39 - 3t)/2 = 15
Answer: Shirts cost $12 each, and ties cost $3 each.

**User:** Solve the system algebraically.
4x - 5y = 3
x = 3 - y
What is the value of x?
9/7
24/14
33/14

**Weegy:** 9/7

**User:** The numerator and denominator of a fraction are in the ratio of 3 to 5. If the numerator and denominator are both increased by 2, the fraction is now equal to .
If n = the numerator and d = the denominator, which of the following systems of equations could be used to solve the problem?
5n = 3d and 3n + 6 = 2d + 4
5n = 3d and 4n + 4 = 3d + 6
3n = 5d and 3n + 6 = 2d + 4

**Weegy:** 3n=5d and 3n 6=2d 4

**User:** 2x + y = 3
x - 2y = -1
If equation one is multiplied by 2 and then the equations are added, the result is _____.
3x = 2
3x = 5
5x = 5

**User:** A boat makes a 120-mile trip downstream in 3 hours but makes the return trip in 4 hours. What is the rate of the current?
3 mph
4 mph
5 mph

**User:** One number is 7 more than twice another. If their difference is 22, what is the larger number?
29
37
43

**Weegy:** let x be the smaller one, then the larger number is (2x + 7). we were given: (2x + 7) - x = 22 x = 22 - 7 = 15 2(15) + 7 = 30 + 7 = 37 the larger number is 37.

**User:** x - 2y = 3
5x + 3y = 2
The lines whose equations are shown intersect at which point?
(1, -1)
(-1, 1)
(0, 3/2)

**Weegy:** .) 2x + y = 3 2.) x - 2y = -1 If equation 1 is multiplied by 2 and then the equations are added, the result is
C.5x = 5

**User:** $6,000 dollars is invested in two different accounts earning 3% and 5% interest. At the end of one year, the two accounts earned $220 in interest. How much money was invested at 3%?
$2,000
$3,000
$4,000

**Weegy:** X+y=6000, 3%x+5%y=220, y=2000. So $2000 Was Invested At 5%. Anonymous

**User:** A boat makes a 120-mile trip downstream in 3 hours but makes the return trip in 4 hours. If b = the rate of the boat in still water and c = the rate of the current, which of the following equations ...
