5x + 6(x - 2) - 8 (x - 3)
Alex Ar [27]

Answer:

The value of x=-4. The figure is also attached below.

Step-by-step explanation:

Considering the expression

5x + 6(x - 2) - 8 (x - 3)

If we have to find the vale of x, then

5x + 6(x - 2) - 8 (x - 3)=0

5x+6x-12-8\left(x-3\right)=0

5x+6x-12-8x+24=0

3x+12=0

\mathrm{Subtract\:}12\mathrm{\:from\:both\:sides}

3x+12-12=0-12

3x=-12

\mathrm{Divide\:both\:sides\:by\:}3

\frac{3x}{3}=\frac{-12}{3}

x=-4

Therefore, the value of x=-4. The figure is also attached below.
