Question

Which of the following equations are equivalent? Select three options.

2+ X=5
Ox+1=4
9+ X= 6
X+(-4)= 7
-5+X=-2

Answer 1

A, B, E

Explanation:

Solve all equations for x. The equivalent equations are the equations that have the same solution.

A 2 + x = 5; x = 3

B x + 1 = 4; x = 3

C 9 + x = 6; x = -3

D x + (-4) = 7; x = 11

E -5 + x = -2; x = 3

Equivalent equations: A, B, E
