• Understanding the differences between equations and inequalities

What is the solution to the equation 8x - 11 = -27?

• x = 2

• x = -2

• x = -3

• x = 3

Why is x = 3 not a solution for the equation 8x - 11 = -27?

• Because 3 is not a valid number

• Because substituting 3 does not satisfy the equation

• Because 3 is greater than -27

• Because 3 is less than -27
