Answer:

Step-by-step explanation:
Isolate x on one side of the equation.
x+11-11=3-11 (Subtract 11 from both sides.)
3-11 (Solve & Simplify.)
3-11=-8
X=-8

So, the correct answer is x=-8.
Okay!
10% of 55 is 5.5
(Butterfly method)
10/100 = n/55
10*55= 550
550/100= 5.50
30% of 900 is 270
30/100 = n/900
30*900 = 27000
27000/100 = 270
25% of 200 is 50
25/100 = n/200
25*200 = 5000
5000/100 = 50
20*4-30
80-30
50
(2*7)+12
14+ 12
26
