Question

Solve the following equations: 2(3x–1)=9(x–2)–7

Answer 1

23/3 or 7 2/3

Explanation:

Answer 2

23/3

Explanation:

So we have the equation:

`2(3x-1)=9(x-2)-7`

First, distribute the left:

`6x-2=9(x-2)-7`

Now, distribute the right:

`6x-2=9x-18-7`

Subtract on the right:

`6x-2=9x-25`

Subtract 9x from both sides:

`-3x-2=-25`

Add 2 to both sides:

`-3x=-23`

Divide both sides by 3:

`x=23/3\approx7.67`

And we're done!
