1/2 x + 36 = 100?

Answer 1

1/2 x + 36 = 100
.5x = 64
x = 128

Answer 2

1/2 x+36 = 100
1/2 x+36-36 = 100-36
1/2 x = 64
x = 2(64)
x = 128

Answer 3

Here's the solution

1/2x + 36 = 100 (First Isolate the variable by subtracting 36 from both sides)
1/2x = 64 (Second, eliminate the coefficient of the variable by multiplying both sides by 2)
(2)1/2x = 64(2)
x = 128

Answer 4

This algebraic equation is very simple so I am assuming that you are having some difficulty with the basics.

The following might help:

Say to yourself I am going to rename 1/2 x to "something"
If you were to rewrite the question you would end up with:

Something plus 36 Equals 100

Without any complicated mathematics you could again rewrite the equation as:

64 plus 36 equals 100

Now we initially decided that "something" was the same as half of x. That is we re-named 1/2 x to "something"

As we know that something is equal to 64 and we know that something is equal to half of x

Then we know that something equals 64 equals half of x

This step above is the key to learning algebra:

We want to know what x is

We know that 64 equals half of x

So 128 must be x

This approach hopefully will help you get started

Answer 5

1/2x +36=100
1/2 x+36-36=100-36
1/2x=64
1/2x(2)=64(2)
x=128

Answer 6

128

Answer 7

128

Answer 8

x = 128

Answer 9

1/2x +36=100
1/2x=64
x = 128

Answer 10

Multiply by 2

x + 72 = 200

Subtract 72 from each side

x = 128
