Question

Which of the following equations are equivalent? Select three options. 2 + x = 5 x + 1 = 4 9 + x = 6 x + (negative 4) = 7 Negative 5 + x = negative 2

Answer 1

2 + x=5, x+1 = 4, and -5 +x = -2 all state that x is equal to 3.

Explanation:

Solve each equation for x. Three of the equations have x = 3, and are therefore equivalent.

2 + x = 5 Equivalent

x = 3

x + 1 = 4 Equivalent

x = 3

9 + x = 6

x = -3

x + (- 4) = 7

x = 11

-5 + x = -2 Equivalent

x = 3
