x+4=6.5

x=2.5

Step-by-step explanation:

It says x increased by 4 which means x+4. It also says x is equal to 6.5 so we write x+4=6.5

Now we solve for x.

x+4=6.5

we can get x by itself by removing the 4

x+4-4=6.5-4

we have to do the same thing to each side to keep the equation equal.

now we can simplify.

x=2.5

X+4=6.5

x=2.5

Step-by-step explanation:

To find value of x, just subtract:

6.5-4=2.5

So the value of x is 2.5
