Question

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

Answer 1

ANSWER

$x=3$

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:

$\begin{gathered} \frac{2x}{2}=\frac{6}{2} \\ x=3 \end{gathered}$

That is the value of x.
