Answer:
Mrs. Asis is 42 years old.
Step-by-step explanation:
Let x be the daughter's age.
Since Mrs. Asis's age is twice as old, the mathematical sentence for this is 2x.
There is a keyword that pertains to the operation to be used: sum, which means we should add up both Mrs. Asis's and her daughter's age to 63.
The completed formula is:
[tex]2x+x=63[/tex]
Now, we need to do simple algebra.
[tex]2x+x=63\\3x=63\\\frac{3x}{3}=\frac{63}{3} \\x=21[/tex]
There we have the daughter's age. We just need to find Mrs. Asis's age by multiplying her daughter's age by 2.
[tex]2x\\2(21)\\42[/tex]
And now we are set. We now know both their ages.
