Question

2(x+3)=x+13
4(5-x)=3x-1
3(x-2)=x+4
5(x-1)=4x+3

Answer 1

2x + 6 = x + 13        2x - x = 13 -6          x = 7
20 - 4x = 3x -1         -4x -3x = -20 -1       7 x = 21            x = 3
3x - 6   = x + 4          3x - x = 6 + 4         2x = 10             x = 5
5x -5   = 4x + 3          5x - 4x = 3 +8        x = 11
