2p+5q = 9
3p-29 =4
solve this in elimination method: multiplication please

Step-by-step explanation:

Given:

2p + 5q = 9

3p - 2q = 4  ( the problem is saying 29 but i'm guessing you meant 2q)

Since the 'q' terms already have opposite signs i'll make them the same to eliminate them

2(2p + 5q = 9)

1) 4p + 10q = 18

5(3p - 2q = 4)

2) 15p -10q =20

now add  1) + 2)

19p = 38

p = 2

now that we know p.. plug it into either equation and solve for q

I'll use the first equation

2(2) + 5q = 9

4 + 5q = 9

5q = 5

q = 1

In Euclidean geometry, the sum of the angles in a triangle always add to 180. In spherical geometry, the sum must be between 180 and 540.

1. adds up to 312  spherical only
2. adds up to 94 neither
3. adds up to 180 Euclidean only
4. adds up to 296 both
