Answer:
i) x + 17 = 54, where x = 37
ii) x + 15 = 54, where x = 39
iii) x + 25 = 54, where x = 29
Step-by-step explanation:
Let's find the sum of 38 and 16.
38 + 16 = 54
We need to find 3 different equations, their sum is 54.
i) x + 17 = 54
To find the x, subtract 17 from both sides, we get
x + 17 -17 = 54 -17
x = 37
37 + 17 = 54
ii) x + 15 = 54
x = 54 -15
x = 39
39 + 15 = 54
iii) x + 25 = 54
Subtracting both sides by 25, we get
x + 25 - 25 = 54 - 25
x = 29
29 + 25 = 54
