Answer:
m = 0
Explanation:
1/2(-1.4m+0.4)=m+0.2
We move all terms to the left:
1/2(-1.4m+0.4)-(m+0.2)=0
Domain of the equation: 2(-1.4m+0.4)!=0
m∈R
We get rid of parentheses
1/2(-1.4m+0.4)-m-0.2=0
We multiply all the terms by the denominator
-m*2(-1.4m+0.4)-(0.2)*2(-1.4m+0.4)+1=0
Wy multiply elements
-2m^2(--(0.2)*2(-1.4m+0.4)+1=0
We use the square of the difference formula
-2m^2(+(0.2)*2(-1.4m+0.4)+1=0
