1) 2(x-0.5) + 1 = 92(x-0.5) = 8x-0.5 = 4x = 4.5
2) 7*(3x+1) - 11x = 221x + 7 - 11x = 210x + 7 = 210x = -5x = -0.5
So, the solutions are:1) x = 4.52) x = -0.5
1) 2(x-0.5) + 1 = 9
2(x-0.5) = 8
x-0.5 = 4
x = 4.5
2) 7*(3x+1) - 11x = 2
21x + 7 - 11x = 2
10x + 7 = 2
10x = -5
x = -0.5
So, the solutions are:
1) x = 4.5
2) x = -0.5
