What value of x makes the equation -6x-20=-2x+4 (1-3×) true

x = 3

Step-by-step explanation:

-6x - 20 = -2x + 4 (1 - 3x)

Distributive property

-6x - 20 = -2x + 4  - 12x

Combine like terms

-6x - 20 = -14x + 4  

Add 14x to both sides

-6x - 20 + 14x = -14x + 4  + 14x

Simplifying

8x - 20 = 4

Add 20 to both sides

8x = 24

Divide both sides by 8

x = 3

Magnitude of vector A=10
Direction angle of vector A=60°

-A/2 is a vector with magnitude equal to the half of the magnitude of the vector A and direction opposite to the direction of vector A, because the minus sign, then:

Magnitude of vector -A/2=Magnitude of vector A / 2 =10/2→
Magnitude of vector -A/2=5

Direction angle of vector -A/2=Direction angle of vector A + 180°=60°+180°→
Direction angle of vector -A/2=240°
