x = 4y = 1Only one solution:x = 1y = 0.25
This is the case when there is only one set of values for each of the variables that satisfies the system of linear equations. It requires the matrix of coefficients. A to be invertible. If the system of equations is y = Ax then the unique solution is x = A-1y.
The expression (1y \times 1y) represents the multiplication of two quantities, each equal to (1y). This can be simplified to (1 \times 1 \times y \times y), which equals (1y^2). Therefore, (1y \times 1y = y^2).
y=5xx2+y2=26Substitute the first equation into the second for y.x2 + (5x)2 = 26x2 + 25x2 = 2626x2 = 26x2 = 1x = SQRT(1) = 1 & -1y = 5*1 = 5y = 5*-1 = -5So the solutions are: (1,5) & (-1, -5)
6-1y+(5y-6y) = 6-y+(-1y) = 6
I think it's 4.8 inches

The algebraic expression of: -x-1y has the same value as -x-y
Here's how it is:2y + 10 = 5y - 4ySolution:2y + 10 = 1y (subtract 5y and 4y)10 = 1y - 2y10 = -1y-1(10 = -1y)y = -10
To simplify this expression, you combine your like terms (9y and 1y). 9y - 1y = 8y 8y - 25 is your answer. It can't be simplified any further than that.
Look at it this way: 1y2 is also shown as 1y x 1y So. if you now replace the 1y for 3ft then you get this: 3ft x 3ft And 3 x 3 = 9 3ft x 3ft = 9ft2 equal to 1y x 1y = 1y2 Hope this helps
Pls, answer thank you :)
