Guidance on Solving Exercise 2 on Page 55 of Math 5 Textbook
Problem:
Find x:
a) x - 5.2 = 1.9 + 3.8
b) x + 2.7 = 8.7 + 4.9
Solution Method:
- Step 1: Calculate the sum on the right side
- Step 2:
a) Hide x as the minuend, so to find the subtrahend, we take the difference added to the subtracted number
b) Hide x as the addend, so to find the unknown addend, we subtract the total from the known addend.
Answer:
a) x - 5.2 = 1.9 + 3.8
x - 5.2 = 5.7
x = 5.7 + 5.2
x = 10.9
b) x + 2.7 = 8.7 + 4.9
x + 2.7 = 13.6
x = 13.6 - 2.7
x = 10.9.
