Question

Check whether the given number is a solution of the equation or
inequality.

13. 2 + 3x = 10; 2

14. 8 + 3b > 15; 2

15. 11y – 5 ≤ 30; 3

Answer 1

Answer:

13. is a solution of the equation. 14. and 15. are both inequalities.

Step-by-step explanation:

the equal sign is something you can look out for to decide if it is a solution to the equation. the > sign means 'greater than' and the ≤ means 'less than' or 'equal to'. both are not equals, therefore they are inequalities.

Answer 2

Step-by-step explanation:

13. 3×2=6 6+2=8

2 is not the solution

14. 3×2=6 6+8=14

14 is not greater than 15 so 2 is not the solution.

15. 11×3=33 33-5=28

3 is the solution
