Solve `a + 0.64 = 8.5` .

to solvean equation we must isolate the variable. In order to "get rid" of +0.64 we must execute the opposite operation, or subtract 0.64 from each side.

`a + 0.64 - 0.64 = 8.5 - 0.64`

`a + 0 = 7.86`

`a = 7.86`

**The solution is a = 7.86.**

This is a linear equation which you can solve in the following way.

`a+0.64=8.5`

Now you take `0.64` from left side and move it to the right side of equal sign and while you do that you must change it's sign from `+` to `-.`

`a=8.5-0.64`

`a=7.86`

**Hence your solution is 7.86.**

a + 0.64 = 8.5 ?

To solve this the variable a must be isolated, this will help us getting the value of the unknown variable a,

a + 0.64 = 8.5

a + 0.64 - 0.64 = 8.5 - 0.64 Subtract 0.64 from both sides

a = 8.5 - 0.64

**a = 7.86 Answer.**

a + 0.64 = 8.5

To solve this equation we have to get " a " by itself first . In order to get " a " by itself subtract .64 on both sides .

By subtracting , you should get

a = 7.86 which is your answer

We need to find out what is the value of a , given that a + 0.64=8.5

This is a linear equation that can be solved very easily.

a + 0.64 = 8.5

To get the variable by it self , we have to undo whatever is being done to it, so subtract .64 from both sides and you get

a = 7.86

a+0.64=8.5

subtract .64 from both sides

a= 7.86

`a+0.64=8.5` minus .64 on both sides

`a+0.64-0.64=8.5-0.64` this will cancel out the .64 on the left and you will have

`a=7.86`
