Question

Choose all of the equations for which x = 1.

A. 2x = 4
B. 3x = 3
C. 4x = 2
D. 4+x= 45
E. 16x = 8
Option 1: B. 3x = 3
Option 2: C. 4x = 2
Option 3: D. 4+x= 45
Option 4: E. 16x = 8

Answer 1

To determine which equations have x = 1, substitute 1 for x in each equation. The equation B. 3x = 3 is true when x = 1.

Step-by-step explanation:

To determine which equations have x = 1, we can substitute 1 for x in each equation and see if the equation is true. Let's go through each option:

1. B. 3x = 3: If we substitute 1 for x, we get 3(1) = 3, which is true.
2. C. 4x = 2: If we substitute 1 for x, we get 4(1) = 2, which is not true.
3. D. 4 + x = 45: If we substitute 1 for x, we get 4 + 1 = 45, which is not true.
4. E. 16x = 8: If we substitute 1 for x, we get 16(1) = 8, which is not true.

Therefore, the equations for which x = 1 are B. 3x = 3.
