3 (2x-1) = 5x+3+7x I do t get this cause I'm stupid

x=-1

Step-by-step explanation:

first you multiply 3 by whats in the parenthesis (you would get 6x-3)

then on the other side you combine like terms (add 7x plus 5x=12x)

Then you would isolate X to one side by subtracting 6x from 12x

Then you would subtract 3 from the side with 12x

By now your equation would be - 6=6x

so you would divide both side by negative six to get x=-1

x=-1

Step-by-step explanation:

3 (2X-1) = 5x+3+7x Distribute the 3 into the parenthesis

6x-3=5x+3+7x Isolate the x on one side

-6x - 6x

-3=5x+3+7x-6x

-3 - 3

-6=5x+7x-6x Add all the x's

-6=6x Divide 6 to isolate x

(-6) / 6 = (6x) / 6

-1=x

Now you can check if it's right by inputting - 1 for x and seeing if the equations equal each other

3 (2 (-1) - 1) = 5 (-1) + 3+7 (-1)

3 (-3) = -5+3-7

-9=-9 They equal each other so x=-1 is correct
