-1(x + 2) = 2(3x - 6)

First, simplify 1 × (x + 2) to (x + 2) / Your problem should look like: -x - 2 = 2(3x - 6)
Second, expand. / Your problem should look like: -x - 2 = 6x - 12
Third, add x to both sides. / Your problem should look like: -2 = 6x - 12 + x
Fourth, simplify 6x - 12 + x to get 7x - 12. / Your problem should look like: -2 = 7x - 12
Fifth, add 12 to both sides. / Your problem should look like: -2 + 12 = 7x
Sixth, add -2 + 12 to get 10. / Your problem should look like: 10 = 7x
Seventh, divide both sides by 7. / Your problem should look like: \frac{10}{7}  = x
Eighth, switch your sides. / Your problem should look like: x =  \frac{10}{7}

Answer: x = \frac{10}{7}

-1(x+2)=2(3x-6)
-1(x+2)=2(3x-6)distributhing -1 through parantheses
-1x+(-1)*2=2(3x-6)
-x-2=2(3x-6) distributhing 2 through parantheses
-x-2=2*3x-2*6
-x-2=6x-2*6
-x-2=6x-12    add x 
-2=6x-12+x
-2=7x-12        add 12
-2+12=7x
10=7x       divide by 7  
x= \frac{10}{7}
Answer : x= 1 3/7

Very fast please!<br><br> How do you work out:<br><br> 5x3/4
Harlamova29_29 [7]
As it is only 5, it is 5/1 so you do 5 x 3 = 15 then 1 x 4 = 4. So 15/4
