Question

1) x-800=0 2) 120•x=0 3) 430:x=430 4) 430+x=430

Answer 1

1)800-800=0
2)120*0=0
3)430:1=430
4)430+0=430

Answer 2

1)x-800=0        2) 120*x=0            3)430/x=430          4)430+x=430
   x=800+0            120*x=0               x=430/430             x=430-430
   x=800                 x=0                     x=1                        x=0
  

Answer 3

1. To solve for x in the equation x-800=0, we add 800 to both sides of the equation to isolate x: x - 800 + 800 = 0 + 800 x = 800 Therefore, x = 800 is the solution to the equation.

2. To solve for x in the equation 120x=0, we divide both sides of the equation by 120: 120x / 120 = 0 / 120 x = 0 Therefore, x = 0 is the solution to the equation.

3. To solve for x in the equation 430/x = 430, we multiply both sides of the equation by x: 430/x * x = 430 * x 430 = 430x Dividing both sides by 430, we get: 430/430 = 430x/430 1 = x Therefore, x = 1 is the solution to the equation.

4. To solve for x in the equation 430 + x = 430, we subtract 430 from both sides of the equation: 430 + x - 430 = 430 - 430 x = 0 Therefore, x = 0 is the solution to the equation.
