Question

For which equations is 8 a solution? Select the four correct answers. x + 6 = 2 x + 2 = 10 x minus 4 = 4 x minus 2 = 10 2 x = 4 3 x = 24 StartFraction x Over 2 EndFraction = 16 StartFraction x Over 8 EndFraction = 1

Answer 1

8 is a solution for the following equations:

x + 6 = 2 (subtracting 6 from both sides gives x = -4)

x - 4 = 4 (adding 4 to both sides gives x = 8)

3x = 24 (dividing both sides by 3 gives x = 8)

StartFraction x Over 8 EndFraction = 1 (multiplying both sides by 8 gives x = 8)

Note that for x+2=10 and x-2=10 and 2x = 4, 8 is not a solution.
