Question

0,2•(m-2)-0,4(m+3)=0,4-0,6m

Answer 1

0,2m-0,4-0,4m-1,2=0,4-0,6m
-1,6-0,2m=0,4-0,6m
-0,2m+0,6m=0,4+1,6
0,4m=2
m=5

Answer 3

To solve the equation 0.2(m-2) - 0.4(m+3) = 0.4 - 0.6m, follow these steps:

Step 1: Distribute the constants and terms within the parentheses. 0.2m - 0.42 - 0.4m - 0.43 = 0.4 - 0.6m

Simplify: 0.2m - 0.8 - 0.4m - 1.2 = 0.4 - 0.6m

Step 2: Combine like terms on both sides of the equation. (0.2m - 0.4m) + (-0.8 - 1.2) = 0.4 - 0.6m

-0.2m - 2 = 0.4 - 0.6m

Step 3: Add 0.6m to both sides of the equation to isolate the variable terms on one side. -0.2m + 0.6m - 2 = 0.4 - 0.6m + 0.6m

0.4m - 2 = 0.4

Step 4: Add 2 to both sides of the equation. 0.4m - 2 + 2 = 0.4 + 2

0.4m = 2.4

Step 5: Divide both sides of the equation by 0.4 to solve for 'm'. 0.4m / 0.4 = 2.4 / 0.4

m = 6

So, the solution to the equation is m = 6.
