Question

0,3m+2(0,2m-0,3)=0,8-0,7(m-2)=

Answer 1

Ответ:

0,3M + 0,4M - 0,6 = 0,8 - 0,7M + 1,4  

0,7M - 0,6 = - 0,7M + 2,2  

0,7M + 0,7M = 2,2 + 0,6  

1,4M = 2,8  

M = 2,8 : 1,4  

M = 2

Answer 2

Ответ:

0,3m+2(0,2m-0,3)=0,8-0,7(m-2)

0,3m+0,4m-0,6=0,8-0,7m+1,4

0,7m-0,6=2,2-0,7m

0,7m+0,7m=2,2+0,6

1,4m=2,8

m=2

Answer 3

Let's solve the equation step by step:

1. Distribute the 2 on the left side: 0.3m + 2(0.2m - 0.3) = 0.8 - 0.7(m - 2)

   This becomes: 0.3m + 0.4m - 0.6 = 0.8 - 0.7(m - 2)

2. Combine like terms on both sides: (0.3m + 0.4m) - 0.6 = 0.8 - 0.7(m - 2)

   This simplifies to: 0.7m - 0.6 = 0.8 - 0.7(m - 2)

3. Distribute the -0.7 on the right side: 0.7m - 0.6 = 0.8 - 0.7m + 1.4

   Now, let's move all the terms involving 'm' to the left side and constants to the right side:

   0.7m + 0.7m = 0.6 + 0.8 + 1.4

   Combine like terms: 1.4m = 2.8

4. Divide by 1.4 to isolate 'm': m = 2.8 / 1.4

   m = 2.0

So, the solution to the equation is m = 2.0.
