x = 20
no.. x equals 11
6x+11=92-3x +3x +3x 9x+11=92 -11 -11 9x=81 divide by 9 x=9
X = Y = 9 The answer must be 9, since it says it in the problem. x = 9, y=9, and x = y are all true based on the given info.
X=45
13
x ≠11 9 + x = 21 9 + x - 9 = 21 - 9 x = 12
-9
11 x 9
3x-11 for x=9
This is not correct. If x=11, then 9+x=20. In order for 9+x=21 to be correct, x would have to be equal to 12.
X= 9
x = -9
X=5Y= 92x + 11= ?2(5)+11=?10+11= 21
-11
11
x+11=2 express first the equation in terms of x, where, x=2-11 then, x=-9 the value of x now is -9.
x+2=11 x+2=-11 x=9 x=-13 x=-13,9
