Step-by-step explanation:

Given

slope (m) = 3

Point

( x1 , y1) = ( 4 , 2)

The equation of line is

y - y1 = m( x - x1)

y - 2 = 3( x - 4)

y - 2 = 3x - 12

3x - y - 12 + 2= 0

3x - y - 10 = 0

Which is the required equation

Hope it will help you :)

Will someone solve for X step by step please?

4(x-2)-3=9

Reorder the terms:
4(-2 + x) + -3 = 9
(-2 * 4 + x * 4) + -3 = 9
(-8 + 4x) + -3 = 9
Reorder the terms:
-8 + -3 + 4x = 9
Combine like terms:
-8 + -3 = -11
-11 + 4x = 9 Solving:
-11 + 4x = 9
Add '11' to each side of the equation.
-11 + 11 + 4x = 9 + 11
Combine like terms: -11 + 11 = 0
0 + 4x = 9 + 11
4x = 9 + 11
Combine like terms:
9 + 11 = 20
4x = 20
Divide each side by 4.

x = 5

Answer:

step 1. Angle bisector theorem.

step 2. 14/6 = 21/ (3x - 12)

step 3. 14(3x - 12) =21(6)

step 4. 6x - 24 = 18

step 5. 6x = 42

step 6. x = 7.
