Question

Solve the following equation for x: 6(4x + 5) = 3(x + 8) + 3.

Answer 1

Answer:

x = -1/7

Decimal form = -0.14285714285

Step-by-step explanation:

$6\left(4x+5\right)=3\left(x+8\right)+3$

$24x+30=3x+27$

$\mathrm{Subtract\:}30\mathrm{\:from\:both\:sides}$

$24x+30-30=3x+27-30$

$\mathrm{Simplify}$

$24x=3x-3$

$\mathrm{Subtract\:}3x\mathrm{\:from\:both\:sides}$

$24x-3x=3x-3-3x$

$\mathrm{Simplify}$

$21x=-3$

$\mathrm{Divide\:both\:sides\:by\:}21$

$\frac{21x}{21}=\frac{-3}{21}$

$x=-\frac{1}{7}$

Answer 2

-7

6•4 = 24x
6• 5= 30

3•X=3x
3•8= 24

24+ 3=27

24x+ 30= 3x+27

Subtract 27 from both sides

24x + 3 =3x

3x- 24x= -21

-21/3= -7
