Which of the following equations are equivalent? check all that apply. a. 2+x=5 b. x+1=4 c. 9+x=6 d. x+(-4)=7 e. -5+x=-2 asap i don't know what this

Hi there!
We are basically asked to solve each equation for x. Here...
A. 
2 + x = 5
-2        -2
x = 3
B.
x + 1 = 4
x = 3
C.
9 + x = 6
x = -3
D.
x + (-4) = 7
x - 4 = 7
x = 11
E.
-5 + x = -2
x = 3
The answer is that equations A, B, and E are equivalent. Hope this helps and have a great day!
