How do I solve -3x=x-(6-2x)?
nydimaria [60]

Answer:

X is 1.

Step-by-step explanation:

-3x = x - ( 6 - 2x )          Distribute the negative sign

-3x = x - 6 +2x               Combine like terms

-3x = 3x -6                     Subtract 3x on both sides

-6x = -6                          Isolate the variable by dividing -6 on both sides

x    =  1

Komok [63]

Answer:

(x+10)(x-10)

Step-by-step explanation:

Given : x^{2} -100

To Find : What are the factors of  x^{2} -100

Solution:

x^{2} -100

Since 100 =10^{2}

x^{2} -10^{2}

using property : a^{2} -b^{2} =(a+b)(a-b)

(x+10)(x-10)

Thus  the factors of x^{2} -100 are (x+10) and (x-10)
