Question

0,3×(х-2)-0,2 (х+4)=0,6

Answer 1

0,3х-0,6-0,2х-0,8=0,6
0,1х-1,4=0,6
0,1х=0,6+1,4
0,1х=2
х=2÷0,1
х=20

Answer 2

To solve the equation, you can follow these steps:

1. Simplify both sides of the equation by multiplying out the brackets and combining like terms:

0.3x - 0.6 - 0.2x - 0.8 = 0.6

0.1x - 1.4 = 0.6

2. Add 1.4 to both sides of the equation to isolate the variable term:

0.1x = 2.0

3. Finally, divide both sides of the equation by 0.1 to solve for x:

x = 20

Therefore, the solution to the equation 0.3×(x-2)-0.2 (x+4)=0.6 is x = 20.
