x - 8 = 12 x - 8 + 8 = 12 + 8 x = 20
x-12
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
If the number is x, then abs(8-x) or |8-x|
3 - 8 + 12 = x -5 + 12 = x 7 = x Answer : 7
x+y=12 x-y =4 x=12-4 =8 8+y=12 y=12-8 =4 so x=8 y=4 8+4=12 8-4=4
x - 8 = 12 x - 8 + 8 = 12 + 8 x = 20
x-12
If the sum of two numbers is 20 and their difference is 4, you can set up the equations: ( x + y = 20 ) and ( x - y = 4 ). By solving these equations simultaneously, you find that ( x = 12 ) and ( y = 8 ). Thus, the two numbers are 12 and 8.
2x - 12 = 8
If x = 8 satisfies the equation 19 - x = 12, then it is a solution of the equation. 19 - x = 12 19 - 8 = ? 12 11 ≠ 12 Since x = 8 does not satisfy the equation, x = 8 it is not a solution.
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
The difference between 8 and 12 is calculated by subtracting the smaller number from the larger number. Thus, 12 - 8 equals 4. Therefore, the difference of 8 and 12 is 4.
It is: 12 minus 8 = 4
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
The 8 times table theoretically has no end, it goes on forever because you can always add another 8 to any number you reach. The first 12 numbers in the table are... 1 x 8 = 8 2 x 8 = 16 3 x 8 = 24 4 x 8 = 32 5 x 8 = 40 6 x 8 = 48 7 x 8 = 56 8 x 8 = 64 9 x 8 = 72 10 x 8 = 80 11 x 8 = 88 12 x 8 = 96.
No, 96 = 12 x 8...
