Step-by-step explanation:
Comment
Let the two numbers be x and y
Equations
x + y = 63
x - y = 12
Solution
Add the two equations. The ys cancel out.
2x = 75 Divide by 2
2x/2 = 75/3 Do the division
x = 37.5
Now use one of the given equations to solve for y
x + y = 63
x = 37.5
37.5 + y = 63 Subtract 37.5 from both sides
37.5-37.5+y= 63 - 37.5 Collect the like terms on both sides
y = 25.5
Check
x - y =? 12
37.5-25.5 =? 12
12 = 12

Answer with explanation:
Income earned by my parents in every two weeks = $ 1046.78
In two weeks there are 14 days, so income earned by my parents in 1 day
Income of my parents after a month, if there are 30 days in a month = $74.77 × 30= $ 2243.10
We, will use ,
rule here , which states that , 28% of monthly income of my parents, should be used for monthly housing expenses ,and 36% of gross monthly income should be used for debt purposes.
28% of $2243.78
= $ 628.26 (Approx)
So,my parents, monthly housing expense should not exceed ≥ $ 628.26
if a plane flies 455 miles with wind, and takes 400 against the wind, and the wind is blowing at a speed of 12mph, then the plane can fly 2455 miles if it's still in the air
