6 + x = -11
6 + x - 6 = - 11 - 6
x = -17
In more detail
First make a mathematical equation from your sentence
6 + x=-11
Now that you have your equation you can solve for 'x'
6+x=-11
-6 -6 (minus 6 from both sides of the equation)
left with x= -17 ( remember a negative plus a negative you get a negative answer)
You can check this by plugging in -17 back in for 'x' in the orginal equation
6+(-17)=-11
6-17=-11
-11=-11
True
therefore x= -17
Hope this helps
x + 6
X=5, x+6, 5+6=11
2x - 6 = x + 5 Isolate x. 2x - x = 6 + 5 x = 11
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
x = -6
x + 6
x=6
11. cuz 5+6=11
x=-6
X=5, x+6, 5+6=11
2x - 6 = x + 5 Isolate x. 2x - x = 6 + 5 x = 11
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
X = 6
x = -6
The patterns is formed from the product of the first number and the absolute difference of the two numbers. 1 x l4 - 1l = 1 x 3 = 3 3 x l7 - 3l = 3 x 4 = 12 6 x l5 - 6l = 6 x 1 = 6 7 x l10 - 7l = 7 x 3 = 21 11 x l7 - 11l = 11 x 4 = 44
2x+5=11 2x=6 x=3
5x+6-2x=-5-x 3x+6=-5-x 4x=-11 x=11/-4
