Move the 8 over
-x=3x-8
Move the 3x over
-x-3x=8
-4x=8
Divide by -4
x=-2
There is a 33.3% chance of rolling a number less than 6. It’s 2/6, which is reduced to 1/3. = that to x/100, multiply 1 x 100, and divide that by 3. So it’s 100 divided by 3, and that’s 33.3, which is the percentage.

-3.7 + w = 9.24
Solving
-3.7 + w = 9.24
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '3.7' to each side of the equation.
-3.7 + 3.7 + w = 9.24 + 3.7
Combine like terms: -3.7 + 3.7 = 0.0
0.0 + w = 9.24 + 3.7
w = 9.24 + 3.7
Combine like terms: 9.24 + 3.7 = 12.94
w = 12.94
Simplifying
w = 12.94</span>
Answer:
x = -3, y = 1
Step-by-step explanation:
To find the value of x and y, find the determinant of original matrix, which would be 21.
Then, substitute the value of x with the solutions to the equations and find the determinant of that matrix, which is -63.
Cramer's rule says that Dx ÷ D is the value of x. So, -63 ÷ 21 = -3.
So, the x-value is -3.
You can find the determinant of the y-value in the same way, and you'll find out that y = 1.
Hope this helped! :)
