Well, a negative times a negative is the same thing as a positive times a positive, so you can basically turn the equation into:
7 x 11 + 22
7 x 11 = 77
77 +22 = 99
So, -7 x -11 + 22 = 99
Hope this helped. :]

x-y = 6 -x-3y = 22 -4y = 28 y = -7 So by substituting: x = -1 and y = -7
15 + 14 + 14 + 11 + 2x + x = 75 Collect like terms 54 + 3x = 75 Subtract 54 3x = 21 Divide by 3 x = 7 ■
y=7+x =x=7-x
x+7 = 2x 2x = x+7 2x-x = 7 x = 7
x-7+7=11+7 x=11+7 x=18
x=-(29/11)
-8 x -11 + (-22) = 88 - 22 = 66
-8 x -11 + (-22) = 88 - 22 = 66
11+2 = 13 and 2*11 = 22 So: x2+13x+22 = (x+2)(x+11) when factored
3 x 7 = 21 2 x 11 = 22 because 3 x 7 = 21 2 x 11 = 22
2772. 308 = 22 x 7 x 11 252 = 22 x 32 x 7 198 = 2 x 32 x 11 lcm = 22 x 32 x 7 x 11 = 2772
x/11 + 21 = 7 x/11 = -14 x = -154
x/11 + 21 = 7 x/11 = -14 x = -154
2 x 7 = 14 2 x 11 = 22 2 x 7 x 11 = 154, the LCM
The factors of 22 are: 1, 2, 11, 22The factors of 77 are: 1, 7, 11, 77The common factors are: 1, 11Factors of 22 and 77 are 1 and 11. Since 22 x 1 = 22, 77 x 1 = 77 and 11 x 2 = 22, 11 x 7 = 77.
