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 = 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)

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)

Solve 7x - 4 = 5x + 15 for x.
**Weegy:** D.{x | x **User:** Solve |x|>5
{-5, 5}
{x|-5 5} **Weegy:** The answer is x=-10..
Solution. x/2 = -5... Multiply both sides by 2 and we get the value of x which is negative 10. **User:** Solve |2x + 1| = 10
**Weegy:** 3(2x + 1) = 3 6x + 3 = 3 6x = 3 - 3 6x = 0 x = 0 (More)

7x - 4 = 5x + 15

7x - 5x = 15 + 4

2x = 19

x = 19/2 = 9.5

7x - 5x = 15 + 4

2x = 19

x = 19/2 = 9.5

|2x + 1| = 10

2x + 1 = 10 or 2x + 1 = -10

2x = 9 or 2x = -11

x = 9/2 or x = -11/2

2x + 1 = 10 or 2x + 1 = -10

2x = 9 or 2x = -11

x = 9/2 or x = -11/2
