Question

Please solve, 7(2-2x)= -13-5x​

Answer 1

`\Huge \boxed{x=3}`

Explanation:

`7(2-2x)= -13-5x`

Expanding brackets.

`14-14x= -13-5x`

Adding 5x and -14 to both sides.

`-14x+5x=-13-14`

`-9x=-27`

Dividing both sides by -9.

`x=3`

Answer 2

`x=3`

Explanation:

We can try and isolate x on one side of the equation to find its value.

First let's apply the distributive property on the left side and get a simpler equation.

`7(2-2x)=-13-5x\\\\14-14x = -13-5x`

Now, to simplify this down, we can add 5x to both sides.

`14-14x + 5x = -13-5x + 5x\\\\14-9x=-13`

Now we can add 13 to both sides:

`14-9x+13=-13+13\\\\27-9x=0`

Now we subtract 27 from both sides:

`27-9x-27=0-27\\\\-9x=-27`

And finally we divide both sides by -9.

`-9x/-9=-27/-9\\\\x=3`

Hope this helped!
