Question

0,7(m+6)-0,4(3-m)=01,9

Answer 1

0,7( m+6)-0,4(3- m)= 1,9
0,7m+ 4,2-1,2-0,4 m
0,7 m +0,4 m + 4,2+1,2=1,9
1,1 m+3=1,9
1,1 m =1,9-3
1,1 m = -1,1
m = -1,1:1,1
m=-1

Answer 2

To solve the equation 0.7(m+6) - 0.4(3-m) = 1.9, follow these steps:

Step 1: Distribute the terms within the parentheses: 0.7m + 0.7(6) - 0.4(3) + 0.4m = 1.9

Simplify the constants: 0.7m + 4.2 - 1.2 + 0.4m = 1.9

Step 2: Combine like terms: 0.7m + 0.4m + 4.2 - 1.2 = 1.9 1.1m + 3 = 1.9

Step 3: Subtract 3 from both sides of the equation to isolate the variable term: 1.1m = 1.9 - 3 1.1m = -1.1

Step 4: Divide both sides by 1.1 to solve for m: m = -1.1 / 1.1 m = -1

So, the solution for the equation is m = -1.
