Question

How do you solve `x - 2.3 = 7.2`?

Answer 1

9.5

Explanation:

first isolate `x`
that is take -2.3 to the other side of the equation. you can do this by adding 2.3 to both sides of the equation.

`x` -2.3 +2.3 = 7.2 + 2.3

this cancels out the -2.3 present in the left hand side of the equation.

which gives us:

`x` = 7.2 + 2.3
`x` = 9.5
