2X - 4 = -10 2X = -6 X = -3

If the number, x, has 10 subtracted from twice it to make 28, then x must be 19. 2x - 10 = 28 2x = 38 x = 19

No.Two matrices A and B can be added or subtracted if and only if they have the same number of rows and columns. That is a 3 x 2 matrix can be added or subtracted only with another 3 x 2 matrix.
X - 6
the first part "number increase by 6" translates to x + 6equals translates to =product of that number and 4 translates to (x + 6)4x + 6 = (x +6)4x + 6 = 4x + 246 = 3x + 24-18 = 3xx = -6===================================Another contributor interpreted the question differently:x + 6 = 4xSubtract 'x' from each side:6 = 3xDivide each side by 3:x = 2
6 x 12 is multiplied to get 72 4 is subtracted from 72 to get the answer 68
Let the number be x: So: 2x-4 = x-10 => 2x-x = 4-10 => x = -6
If you are looking for what number it is, it can be described by this equation: 2x-12=6. Solving this equation x=9.
2X - 4 = -10 2X = -6 X = -3
X-1

(X - 30) does.
