Distributive Property (5): \(\displaystyle \L \;15x-5-6x=3x-2\)

Simpilication: \(\displaystyle \L \;9x-5=3x-2\)

Subtraction Property (3x): \(\displaystyle \L \;6x-5=-2\)

Addition Property (5): \(\displaystyle \L \;6x=3\)

Division Property (6): \(\displaystyle \L \;x=\frac{1}{2}\)

Distributive Property: \(\displaystyle \L \;40-5x=3x\)

Addition Property: \(\displaystyle \L \;40=8x\)

Division Property (8): \(\displaystyle \L \;x=5\)

Distributive Property (3): \(\displaystyle \L \;5x=3x-18\)

Subtraction Property (3x): \(\displaystyle \L 2x=-18\)

Division Property: \(\displaystyle \L \;x= - 9\)

same problem.

4) 4(3x+5)=18x

5) 4(x+3)=12x-2

6) 5x+2(3x-4)=14x+7

These are some tricky problems eh?

Not really; they're fairly straight-forward. And you've already had half of the posted exercises completed for you. Now it's your turn to show some effort.crappiefisher26 said:These are some tricky problems eh?

Please attempt these exercises. If you get stuck, please reply clearly showing (line by line) what you have tried and how far you have gotten.

Thank you.

4(x+3)=12x-2

4x+12=12x-2

subtracted 12x on each side

-8x+12=-2

subtracted 12 on each side

-8x=-14

divided by -8x on each side

got x=1.75 or 1 3/4. Is that correct? I believe so.

4(3x+5)=18x

got 12x+20=18x

subtracted 12x on each side

20=6x

divided by 6x on each side and got 3.33 repeating. would the answer just be 20/6?

Fill it back in to see: \(\displaystyle \;-8(1\frac{3}{4})+12= -2\, \to\, -14+12=-2\,\to\, -2= -2\)crappiefisher26 said:

So yes that is correct. Do this w/your other problems as well to make sure you do not make a simple mistake.

You do not have it in simpiest form. You should find the LCM (which in this case is 2).crappiefisher26 said:4(3x+5)=18x

Hence: \(\displaystyle \frac{20}{6}\, \to\, \frac{10}{3}\)
