How to sole linear equations

Mathematics

Answer:

Step-by-step explanation:

I assume you mean simple linear equations, maybe not factoring. Anyhow Ill do a few examples:

1. 2x + 5 = 19

2. 14 - 3x = 23

3. 50x / 5 = 150

1. 2x + 5 = 19

Subtract 5

2x = 14

Divide by 2

x = 7

2. 14 - 3x = 23

Subtract 14 to the other side because we have to isolate the term with x in it

-3x = 9

Divide by -3

x = -3

3. 50x / 5 = 150

Multiply by 5 to isolate the value with x

50x = 750

Divide by 50

x = 15

I dont know if this is what you are looking for but this is general idea of how to solve these types of questions. If you need factoring or help with quadratics then let me know!

36 equally-likely outcome: (1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1),(6,2), (6,3), (6,4), (6,5), (6,6)

Solution:
Outcomes with first number being old number and second being even number: (1,2), (1,4), (1,6), (3,2), (3,4), (3,6), (5,2), (5,4), (5,6) = 9 outcomes

P(old,even) = 9/36 =1/4 = 0.25
