Let's solve for x in each equation:
1) 5 = 4x - 3x5 = x
2) x + 3 = 3x - 7x + 10 = 3x10 = 2xx = 5
3) 3 - (x - 1) = 03 - x + 1 = 04 - x = 04 = x
Therefore, x = 5, x = 5, x = 4.
Let's solve for x in each equation:
1) 5 = 4x - 3x
5 = x
2) x + 3 = 3x - 7
x + 10 = 3x
10 = 2x
x = 5
3) 3 - (x - 1) = 0
3 - x + 1 = 0
4 - x = 0
4 = x
Therefore, x = 5, x = 5, x = 4.
