Question

What is the value of x in this equation? 3(2x - 5) - 4x + 8 = -1

Answer 1

`x=3`

Step-by-step explanation

We want to find the value of x in the equation:

`3(2x-5)-4x+8=-1`

First, expand the bracket:

`6x-15-4x+8=-1`

Next, collect like terms:

`\begin{gathered} 6x-4x-15+8=-1 \\ 2x-7=-1 \end{gathered}`

Next, add 7 to both sides of the equation:

`\begin{gathered} 2x-7+7=-1+7 \\ 2x=6 \end{gathered}`

Finally, divide both sides by 2:

`\begin{gathered} (2x)/(2)=(6)/(2) \\ x=3 \end{gathered}`

That is the value of x.
