Find the slope of the line whose equation is 6x - 3y = 12.
**Weegy:** The answer would be y = 2 (x+2). **User:** px + qy = r
2px - qy = 2r
When solving this system of equations, x =
**Weegy:** If r = px + qy and 2px - qy = 2r
then..
2px - qy = 2 (px + qy)
2px - qy = 2px + 2qy
- > - qy = 2qy
- - > qy = 0
If qy = 0 then 2px = 2r and px = r **User:** 3x + 2y = 4
2x - y = 5

**User:** One number is 6 more than twice another. If their sum is 51, find the numbers.
Which of the following systems of equations represents the word problem?
y = 2x + 6 and y = x + 51
y = 2x + 6 and x + y = 51
y = 2(x + 6) and x + y = 51 **Weegy:** This is an easy mathematical problem. In order to find the slope and the Y intercept of the equation all you need to do is bring the equation in the general form, y = mx + c. It will become y = 2x - 5. [ [ In this case as we can see 2 is the slope and -5 is the y intercept. ] ] **User:** 2x - y = 10

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.

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 = 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 = 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)

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)

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
