Given :
- if 8 is added to 4 times a number the result is two less than 5 times a number.
To Find :
- The another number.
Solution :
Let, the number be (x)
According to the question :
- If 8 is added to 4 times a number = (8 + 4x)
- The result is 2 less than 5 times a number = (5x - 2)
༒ 8 + 4x = 5x - 2
⪼ 8 + 2 = 5x - 4x
⪼ 10 = x
Verification :
- Putting (x = 10) in (8 + 4x = 5x - 2)
⪼ 8 + 4x = 5x - 2
⪼ 8 + 4(10) = 5(10) - 2
⪼ 8 + 40 = 50 - 2
⪼ 48 = 48
LHS = RHS
Hence Verified
