ruslelena [56]

Answer:

x = 6

Step-by-step explanation:

−16=−4(2x−8)

<u>Let's rearrange so solving would be easier.</u>

-4(2x-8) = -16

<u>Let's open the brackets. Please take note of the signs (+) (-).</u>

(-4 * 2x) + (-4 * -8) = -16

-8x + 32 = -16

<u>Subtract </u><u>32</u><u> from both sides. Please take note of the signs (+) (-).</u>

-8x + 32 (-32) = -16 (-32)

-8x + 0 = = -48

-8x = -48

<u>Divide both sides by </u><u>-8</u><u>.</u>

-8x/-8 = -48/-8

x = 6
