Question

Look at step by step solution shown below and fill in the missing step

Answer 1

The Solution:

We are given the equation below:

`-3(2x-5)-2x+6=-19`

Clearing the bracket, we get

`-6x+15-2x+6=-19`

We are required to show the missing step, which is obtained by collecting the like terms.

`\begin{gathered} -6x-2x+15+6=-19 \\ -8x+21=-19 \\ \text{Subtracting 21 from both sides, we get} \\ -8x+21-21=-19-21 \\ -8x=-40 \end{gathered}`

Dividing both sides by -8, we get

`\begin{gathered} (-8x)/(-8)=(-40)/(-8) \\ \\ x=5 \end{gathered}`

Therefore, the value of x is 5.
