Question

What should be added to 4.289 to get 11​

Answer 1

Let the number which should be added is x

ATQ

$\\ \sf\longmapsto x+4.289=11$

• Take 4.289 to right

$\\ \sf\longmapsto x=11-4.289$

$\\ \sf\longmapsto x=6.711$

6.711 should be added to 4.289 to get 11

Answer 2

$\huge\text{Hey there!}$

$\large\text{We do not know the unknown number just yet so we will label it}\\\large\text{as the variable of \boxed{\bf n}}\large\text{ until we find the result of the unknown}\\\large\text{number}$

$\large\text{So, your equation is now: \underline{\underline{n + 4.289 = 11}} or \underline{\underline{4.289 + n = 11}}}$

$\large\textsf{n + 4.289 = 11}\\\large\text{SUBTRACT \underline{4.289} to BOTH SIDES}\\\large\text{n + 4.289 - 4.289 = 11 - 4.289}\\\large\text{CANCEL out: 4.289 - 4.289 because that gives you 0}\\\large\text{KEEP: 11 - 4.289 because that helps you get the n-value}\\\large\text{SIMPLIFY ABOVE AND YOU HAVE YOUR RESULT}\\\large\text{n = \bf 6.711}\\\\\boxed{\boxed{\huge\text{Therefore, your answer is: \bf 6.711}}}\huge\checkmark$
