Oh, what a lovely question! To solve by Cramer's rule, you'll first calculate the determinant of the coefficient matrix, then create matrices by replacing the x-column with the constants and solving for the determinant of that matrix. Finally, you'll divide these determinants to find the values of x and y. Just like painting a happy little tree, take your time and follow each step with care.

What is 4x squared y plus 3x squared y?
4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)
Factor x2y - xyb - abx plus ab2?
4
What is the coefficient of the x2y term in the expansion of (x plus 2y)3?
The coefficient is 6.
What is like terms in polynomial?
They are terms in which a variable is raised to the same power (index) in both terms. So x2y and -27x2y are like terms but not xy2.
What is the point of intersection of y equals 2x-x2 and y equals 0?
y = 2x - x2y = 0Since both quantities on the right side are equal to 'y', they're equal to each other.2x - x2 = 0x (2 - x) = 0x = 0and2 - x = 0x = 2The two points of intersection are (0, 0) and (2, 0) .
How do you solve 8 plus x2y?
i don't get that if it is 2xy +8 or 8 + 2xy then you can't solve or simplify it any further if it were 8 x 2y then you time the 8 by the 2 to get 16y
Simplify 8 -x 2y you 2y - x?
8-x2y 8-2xy 2xy-8
Solve the equation y' plus x2y equals x2?
(2x)ysquared
What is -2y plus x2y-8?
It is -2y + x2y - 8, which is an expression that cannot be simplified further, not can it be evaluated.
If I know that x2y plus 4 and I plug that into 3y plus 5x what do I get?
You will get nonsense. You cannot plug x2y + 4 into anything!
What is 4x squared y plus 3x squared y?
4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)
Square root of 2xy times 14x3y?
Do the multiplication, then take the square root. After the multiplication, you get 28x4y2. The square root of 28 is 2 times the root of 7, the square root of x4 is x2, and the root of y2 is y. So, the final result is 2 times square root of 7, times x2y.
What is the greatest common factor of x2y and xy2?
xy
What is the GCF of x2y and xy2?
The GCF is xy
What is 4xy plus x3y plus yx2 plus yx plus 3yx simplified?
4xy + x3y + yx2 + yx + 3yx = x3y + x2y + 8xy = (xy)(x2y + x + 8)
