Answer 2

a) To solve the equation 3x - 10x - 9x + 4 = 0, first, combine like terms:

3x - 10x - 9x + 4 = -16x + 4 = 0

Now, isolate the variable x:

-16x = -4

Next, divide both sides by -16 to find the value of x:

x = -4 / -16

x = 1/4

b) To solve the equation x + x - x + x - 2 = 0, combine like terms:

x + x - x + x - 2 = 2x - 2 = 0

Now, isolate the variable x:

2x = 2

Next, divide both sides by 2 to find the value of x:

x = 2 / 2

x = 1

So the solution for both equations is:

a) x = 1/4 b) x = 1
