Question
Find ๐ฅ,ย ๐ฆ,ย ๐ง such that (๐ฅ-๐ฆ,ย ๐ฅ+๐ฆ,ย ๐ง-1)=(4,2,3)
Solution
From the given equation, we have three separate equations:
- ๐ฅ - ๐ฆ = 4
- ๐ฅ + ๐ฆ = 2
- ๐ง - 1 = 3
Let's solve these equations one by one:
- From the first equation, we can express ๐ฆ in terms of ๐ฅ: ๐ฆ = ๐ฅ - 4
- Substitute ๐ฆ = ๐ฅ - 4 into the second equation: ๐ฅ + (๐ฅ - 4) = 2, which simplifies to 2๐ฅ - 4 = 2. Solving for ๐ฅ gives ๐ฅ = 3.
- Substitute ๐ฅ = 3 into ๐ฆ = ๐ฅ - 4 to find ๐ฆ = 3 - 4 = -1.
- From the third equation, we can solve for ๐ง: ๐ง = 3 + 1 = 4.
So, the solution to the system of equations is ๐ฅ = 3, ๐ฆ = -1, ๐ง = 4.
