What is unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Total number of carpets Mr. Cullenneed =91 carpet squares

Total number of carpets Mr. Cullen have= 49 carpet squares.

number of carpets Mr. Cullen need to complete

=91 - 49

= 42 carpets squares

So, Mr. Cullen needs 42 carpets squares.

Is anyone good at elimination method? I will give 10 points to the person that answer the question. :)Jill wants to solve the following system using the elimination method:

y = x + 8
y = 3x − 11

What number should the equation y = x + 8 be multiplied by to eliminate x?

Answers

To eliminate x, the coefficients of x's in both equations should be opposite numbers. Since the coefficient of x in the second equation is 3, the coefficient in the first equation should be -3. So she should multiply the first equation by -3.
-3! 
-3y=-3x-24
y=3x-11
-2y=-35
y=17.5
