Question

I need help with these 4 problems

Answer 1

To find out if the given value is a solution of the equation, substitute/plug it in to see if it equals out:

1. 34 + x = 46; x = 12      Plug in 12 into "x" since x = 12

34 + 12 = 46

46 = 46        

The given value is a solution of the equation because it does equal 46

2. y - 9 = 14; y = 22      Plug in 22 into "y" since y = 22

22 - 9 = 14

13 = 14

The given value is not a solution of the equation because 22 - 9 equals 13 not 14

3. 6d = 54; d = 9      Plug in 9 into "d" since d = 9

6(9) = 54

54 = 54

The given value is a solution of the equation because it does equal 54

4. $\frac{n}{3} =13$  ; n = 39     Plug in 39 into "n" since n = 39

$\frac{39}{3} =13$

13 = 13

The given value is a solution of the equation because it does equal 13
