Question
Verify by substitution that:
x = 4 is the root of 3x - 5 = 7
x = 4 is the root of 3x - 5 = 7
✓
Answer
x = 4 is the root of 3x - 5 = 7
Now, substituting x = 4 in place of ‘x’ in the given equation:
3x - 5 = 7
3(4) - 5 = 7
12 - 5 = 7
7 = 7
Since, L.H.S. = R.H.S.
Hence, x = 4 is the root of 3x - 5 = 7
Now, substituting x = 4 in place of ‘x’ in the given equation:
3x - 5 = 7
3(4) - 5 = 7
12 - 5 = 7
7 = 7
Since, L.H.S. = R.H.S.
Hence, x = 4 is the root of 3x - 5 = 7
