Which of the following equations are equivalent (i.e. have the same solution for x)? Check all that apply.A X+1=4B 9+X=6C -5+x=-2D 2+x=5E X+(-4)=7

Respuesta :

Solve the following equations and find those that have the same solution for x.

A

x + 1 = 4

Subtracting 1:

x = 3

B

9 + x = 6

Subtracting 9:

x = -3

C

-5 + x = -2

Adding 5:

x = 3

D

2 + x = 5

Subtracting 2:

x = 3

E

x + (-4) = 7

Operating:

x - 4 = 7

Adding 4:

x = 11

Only equations A, C, and D are equivalent
