Question

For which equation is 7 a solution​

Answer 1

3x + 1 = 27

3(7) + 1 = 27

21 + 1 = 27

22 ≠ 27

FALSE

3(x + 1) = 24

3(7 + 1) = 24

3(8) = 24

24 = 24

TRUE

2x + 3(x - 4) = 21

2(7) + 3(7 - 4) = 21

14 + 3(3) = 21

14 + 9 = 21

23 ≠ 21

FALSE

x^2 - 8 = 42

7^2 - 8 = 42

49 - 8 = 42

41 ≠ 42

FALSE
