px + qy = r
2px - qy = 2r
adding up the above equations the result is:
3px = 3r
px = r
x = r/p
px + qy = r 2px - qy = 2r When solving this system of equations, x = r/p.

3x + 2y = 4 (equation 1)
2x - y = 5 multiple 2 on both sides:
4x - 2y = 10 (equation 2)
adding up equation 1 and 2 the result is:
7x = 14
x = 2,
y = 2x - 5 = 4 - 5 = -1
The only one solution for the system 3x + 2y = 4 2x - y = 5 is (2, -1)

2x - y = 10
y = -x - 1
institute y in the first equation:
2x - (-x - 1) = 10
2x + x + 1 = 10
3x = 9
x = 3,
y = -3 - 1 = -4
The solution for the system 2x - y = 10 y = -x - 1 is (3, -4)

2x + y = 7
5x + y = 9
subtracting the two equations the result is:
3x = 2
x = 2/3;
2(2/3) + y = 7
4/3 + y = 7
y = 7 - 4/3 = 21/3 - 4/3 = 17/3
The solution for the system 2x + y = 7 5x + y = 9 is (2/3, 17/3)

3x - y = -4
x + y = 0
adding up the equations the result is:
4x = -4
x = -1,
3(-1) - y = -4
y = -3 + 4 = 1
The solution for the system 3x - y = -4 x + y = 0 is (-1, 1)

On a trip, the fare was 50¢ for each adult and 25¢ for each child. If 30 passengers paid $12.25, how many adults and children went? Which of the following equations could not be used to solve the problem?
Weegy: 25x + 50x = 30(1225) is the answer. a = adult, [ c = child a + c = 30 or 30 - c = a .5a + .25c = 12.25 .5(30 - c) + .25c = 12.25 15 - .5c + .25c = 12.25 -.25c = -2.75 c = 11 a = 30 - c = 30 - 11 = 19 ] (More)
