Question

n+12=20 12,8,20,0 class 6 Exercises 11.5​

Answer 1

Step-by-step explanation:

n + 12 = 20

n = 8 is a solution for this equation because for n = 8, n + 12 = 8 + 12 = 20

n = 12 is not a solution for this equation because for n = 12, n + 12 = 12 + 12 = 24 and not 20

n = 20 is not a solution for this equation because for n = 20, n + 12 = 20 + 12 = 32 and not 20

n = 0 is not a solution for this equation because for n = 0, n + 12 = 0 + 12 = 12 and not 20
