Understand the Problem
You're asking to solve the equation 2 + x = 5 for the variable 'x'. This involves isolating 'x' on one side of the equation.
Answer
$x = 3$
Answer for screen readers
$x = 3$
Steps to Solve
-
Isolate x To isolate $x$, we need to subtract 2 from both sides of the equation to maintain equality. $$2 + x = 5$$
-
Subtract 2 from both sides Subtracting 2 from both sides gives us: $$2 + x - 2 = 5 - 2$$
-
Simplify the equation Simplifying the equation, we get: $$x = 3$$
$x = 3$
More Information
The solution to the equation $2 + x = 5$ is $x = 3$. This means that if you substitute 3 for $x$ in the original equation, you get a true statement: $2 + 3 = 5$.
Tips
A common mistake is to add 2 to both sides instead of subtracting. Remember to perform the opposite operation to isolate the variable. Another common mistake is to only subtract from one side, and not the other. You must perform the same operation to both sides of the equation to keep it balanced.
