Answer 2

1) (x+6)+(x-5.4)=0 2x + 0.6 = 0 2x = -0.6 x = -0.3

2) (5.4+x)+(10-x)=0 15.4 = 0 This equation has no solution.

3) 10(x-3)=0 x-3=0 x=3

4) (5-x)x=0 5x - x^2 = 0 x(5 - x) = 0 x=0 or x=5

5) (4.2-x) * (-4.2+7-x) = 0 (-4.2 + x)(2.8 - x) = 0 x = -4.2 or x = 2.8

So, the solutions to the given equations are x = -0.3, 3, 0, 5, -4.2, and 2.8.
