Which number(s) below belong to the solution set of the equation? Check all
that apply.
X+ 6 = 45
A. 45
B. 39
C. 35
D. 3
E. 51
F.0
Answer: B
Explanation:
Since X + 6 = 45 you subtract 6 from both sides.
X+6 (-6) = 45 (-6)
The +6 and -6 cancel out and you are left with X=45-6
45-6=39
So X=39 (Choice B)
X+6=45
X=45-6
X=39
La réponse est le B
