8^4x=135
log(8^4x)=log(135
4x*(log(8))=log(135)
4x=log(135)/log(8)
4x=2.358939
4x/4=2.358939/4
x=0.589735

Value of x for 12(x-2)+3x=1/2(x+6)+2​
Damm [24]

Answer:

The value of x = 2

Step-by-step explanation:

Given the equation

12\left(x-2\right)+3x=\frac{1}{2}\left(x+6\right)+2

  • Expand 12(x-2) = 12x - 24
  • Expand 1/2(x+6) = 1/2x + 3

so the equation becomes

12x-24+3x=\frac{1}{2}x+3+2

simplifying

15x-24=\frac{1}{2}x+5

15x=\frac{1}{2}x+29

multiplying both sides by 2

30x = x + 58

subtracting x from both sides

30x - x = 58 - x

29x = 58

divide both sides by 29

\frac{29x}{29}=\frac{58}{29}

simplifying

x = 2

Therefore, the value of x = 2

A first number plus twice a second number is 24. twice the first number plus the second totals 21. find the numbers.
Ulleksa [173]
We do like the following:
Set the first number is a and the second is b.
We have two equations: a+2xb=24, 2xa+b=21
And we have 2xa+4xb=48 or 2xa=48-4xb
So: 48-4xb+b=21 or -3xb=21-48=-27 and we got b=-27:(-3)=9 and a= 6
a=6 and b=9
