Question

8x-16+8x=16? what do i do to solve this problem?

Answer 1

you add like terms

8x -16 + 8x = 16

16x -16 = 16

add 16 to both sides

16x = 32

isolate x(divide by 16)

x=2  

Answer 2

8x-16+8x=16

8x+8x=32

16x=32

x=2

Answer 3

Okey dokey...so what you basically have to do, it simplify. That is, get all the (x)s together.

Like so.

8x-16+8x=16

Add the two (8x)s together....and you get 16x

16x - 16 = 16

Now you can get rid of the (-16) by adding it to the other side of the equation

16x = 32

So just divide both sides by 16, to get x by itself, and voila!

x = 2

Answer 4

You want to combine like terms. Meaning add the x's. So 8x+8x=16x. So you have 16x-16=16. Then you want to get x by itself. So add 16 to both sides.... 16x-16+16=16+16 ----> simplifies to 16x=32. Then divide both sides by 16. So 16/16=1 and 32/16=2....soooo x=2! yay!  

Answer 5

first conbine the 8xs to get 16x then add negative 16 to other side to get 32 now it looks like this : 16x=32 then divide on both sides by 16 16x divided by 16 is x 32 divided by 16 is 2, so x=2

Answer 6

8x - 16 + 8x = 16

16x = 16 + 16

x = 1 + 1

x = 2

Answer: x = 2

Proof:

8(2) - 16 + 8(2) = 16

16 - 16 + 16 = 16

16 = 16

Answer 7

8x+8x=16+16

16x=32

x=2

Answer 8

combine like terms: 16x - 16 = 16

add 16 to both sides: 16x = 32

divide each side by 16 (the number multiplying x): x = 2

Answer 9

Add 16 to both sides

8x-16+8=16

   +16    +16

8x+8x=32

combine like terms

16x=32

divide both sides by 16

16x=32

16   16

x=2

Answer 10

I love mnemonics in maths, so I will teach you mine

8x - 16 + 8x = 16

group the like terms together, it makes complex equations more clear

8x + 8x - 16 = 16

now it's much easier to add/subtract the terms,

take out the common factor (x) out, and put add/subtract their scalars in ()...  a "scalar" is the number , eg (8), infront of the variable (x)

(8 + 8)x - 16 = 16

16x - 16 = 16

now "carry" (-16) on the left over to the right,

then change its operator (-) to its opposite (+), meaning:

(-16) carried over change to (+16)

16x = 16 + 16

16x = 32

now, carry over the scalar (16) of (x), and

then flip it upside-down and multiply the other by it, eg:

(16) = (16/1) and the reciprocal is (1/16), "upside-down"--16

x = 32 * 1/16

x = 32/16

x = 2/1

x = 2

--------

TIP: the reciprocal of a whole number is a (-1)--exponent, eg:

16 = 16^1 = 16/1, the reciprocal is 16^(-1) = 1/16

a negative exponent is the reciprocal of that fraction in positive exponent:

3^(-2) = 1/(3^2) = 1/9

--------

I hope this helps

be good

Answer 11

8x-16+8x=16

8x+8x=16+16

16 x = 32

x=32/16

x= 2

Answer 12

8x+8x=32

16x=32

x=2

Answer 13

Combining like terms,

16x - 16 = 16

16x = 32

x = 2
