Which property was used to write the equation in step 2?
ankoles [38]

For this case we have that by definition, the distributive property establishes that:

a (b + c) = ab + ac

So, if we have:

5 (x-7) = 55

When applying distributive property to the terms within the parenthesis we have:

5x-35 = 55

The distributive property was used to write the second step.

Answer:

Distributive property

Solve for x and explain the steps:<br> 3x-6=4(2-3x)-8x
mote1985 [20]

Answer: x = 14/23

Step-by-step explanation:

3x-6=4(2-3x)-8x

3x-6=8-12x-8x --> Expand 4(2-3x)

3x-6=8-20x --> Collect like terms

3x-6+6=8-20x+6 --> Add 6 to both sides, to remove it from the right side

3x=-20x+14

3x+20x=-20x+14+20x --> Add 20x to both sides, to remove it from the left side

23x=14

\frac{23x}{23}=\frac{14}{23} --> Divide both sides by 23

x = 14/23
