Summary In this lesson, you learned how to evaluate linear equations at a specific value of x. You also learned to determine whether particular values of x are solutions to linear equations and inequalities in one variable.
Find someone who Can give the value of x so that x + 3 = 5 is a true equation. Can determine the smallest integer value for x that can hold x > 1.5 true. Can solve by guess and check for the solution of 9x – 1=8. Can give the value of 3x – 1 if x = 3. Can give the numerical value of 3(22 – 32). Knows which is greater between x3 and 3x when x = 2. Can translate the phrase ‘a number x increased by 3 is 2’ to algebraic expression. Can determine which of these {0,1, 2,…, 8, 9} is/are solution/s of 3x < 9. Can write an inequality for which all positive numbers are NOT solutions. Knows the largest integer value of x that can satisfy the inequality 2x – 1 < 3? Knows what Arabic word is known to be the origin of the word Algebra. Can write an equation that is true when x = 4. Can write a simple inequality that will is satisfied by the elements in the set {–1, 0, 1.1, , 3, 4, …}. Can name the set of numbers satisfying the inequality x < 0. Can explain what an open sentence is. Can give the positive integer values of x that can satisfy x + 3 < 6. Summary In this lesson, you learned how to evaluate linear equations at a specific value of x. You also learned to determine whether particular values of x are solutions to linear equations and inequalities in one variable.
