-2(3x-2.4)=-3(3x-2.4)

Answer 1

Interesting problem. Both Philip and Ashley have answered it correctly. I wanted to illustrate something about this problem by first setting y = (3x-2).

-2(3x-2.4) = -3(3x-2.4)

Substituting y we get:

-2(y) = -3(y)

Whoa, how can -2y = -3y ??

Well, only if y = 0.

y = (3x-2.4)

3x - 2.4 = 0

x = 2.4/3

x = 0.8

Same answer, just a different approach. The proper approach is to complete the calculations as per Ashley and Philip. My contribution is to illustrate a different thought process that also provides an answer.

Answer 2

First you would distribute the coefficient outside the parentheses on each side to get -6x+4.8=-9x+7.2. Then we need to combine like terms by adding 9x to both sides to get 3x+4.8=7.2. Next we combine the constants by subtracting 4.8 from each side to get 3x=2.4. Lastly, we divide both sides by 3 to isolate the variable and get x=0.8.

Answer 3

-2(3x-2.4) = -3(3x-2.4)

This can only be true if:

3x - 2.4 = 0

Solve for x.
