We'll the answer is x=4

How I found it:
1st I converted mixed numbers into improper fractions
2nd Multiplied both sides by 2
-(x+2)+3x=6
2x-2=6
then i added 2 to both sides
2x=8
then to get rid of 2 from x, i divided 2x/2=8/2
and then my answer became x=4
I hope this helps you out. Good Luck =)

Answer:

$\underline{ \boxed{z\overline{z} = 34}}$

Step-by-step explanation:

$if \: z = -3 + 5i \\then \: \overline{z} = - (3 + 5i) \\ hence \: z\overline{z} = (-3 + 5i)( - 3 - 5i) \\ z\overline{z} = 9 + 15i - 15i - {(5i)}^{2} \\ z\overline{z} = 9 - (25 ){i}^{2} \\ z\overline{z} = 9 - (25)( - 1) \\ z\overline{z} = 9 + 25 \\ \underline{ \boxed{z\overline{z} = 34}}$

DochEvi [55]

$64^x = 16^{x-1} \\\\ (4^3)^x=(4^2)^{x-1} \\\\ 4^{3x}=4^{2x-2}\\\\ 3x=2x-2 \\\\ \boxed{x=-2}$

Here is a system of equations Y= 2x Y= -1/2x + 5 Determine whether (2,4) is a solution to this system Use Algebra to show whethe

gregori [183]

Answer: (2,4) is a solution to this system

Step-by-step explanation:

The given system of equations is expressed as

y = 2x - - - - - - - - - - - 1

y = -1/2x + 5 - - - - - - - - - 2

The first step is to equate equation 1 to equation 2. It becomes

2x = - 1/2x + 5

The next step is to add - 1/2x to the left hand side and the right hand side of the equation. It becomes

2x + x/2 = - x/2 + x/2 + 5

(4x + 2)/2 = 5

The next step is to multiply the left hand side and the right hand side of the equation by 2. It becomes

(4x + 2)/2 × 2= 5 × 2

4x + 2 = 10

Subtracting 2 from the left hand side and the right hand side of the equation. It becomes

4x + 2 - 2 = 10 - 2

4x = 8

Dividing the left hand side and the right hand side of the equation by 4, It becomes

4x/4 = 8/4

x = 8/4 = 2

Substituting x = 2 into equation 1, it becomes

y = 2 × 2 = 4
