Answer:
x+4=6.5
x=2.5
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
