Question

There is a mistake in each fraction-

please describe what went wrong (all of em)
No huge explanation needed- just answers- PLEASE!!!!
Would give more pts if i had them

Answer 1

1) They forgot to multiply 2 times (2x+5)

2) x-2 is not equal to -(x+2).

3) The correct expression is
`x-1-1+2x=1-3x`

4) The correct way is
`4(2x+3)=3(1-3x)`

Explanation:

1) In this case they forgot to multiply 2 times (2x+5). Let's recall we need to multiply (2x+5) to all terms of the equation.

2) Here, x-2 is not equal to -(x+2). If we see -(x+2) = -x-2 using the distributive property.

3) After multiplying by (3x-2) we will have:

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

Apply the distributive property again, we will have:

`x-1-1+2x=1-3x`

So the correct term is 2x not -2x.

4) When we multiply by (1-3x)(2x+3) on each side of the equation, we will have something like this:

`(4(1-3x)(2x+3))/((1-3x))=(3(1-3x)(2x+3))/((2x+3))`

If we see we can simplify the same terms on each side of the equation.

`4(2x+3)=3(1-3x)`

This is the correct way to do this.

I hope it helps you!
