Answer:
The answer is;
x=-4.12
Step-by-step explanation:
Solving;
-2(x+4.1)=x+2 x+12.3
Step 1
Consider the equation on the left hand side;
-2(x+4.1)
Step 2
Open the brackets
(-2×x)+(-2×4.1)
-2 x+(-8.2
-2 x-8.2...equation 1
Step 3
Consider the equation on the right hand side
x+2 x+12.3
Collect the like terms and solve
(x+2 x)+12.3
3 x+12.3...equation 2
Step 4
Equate equation 1 and 2
-2 x-8.2=3 x+12.3
Collect the like terms
-2 x-3 x=12.4+8.2
-5 x=20.6
divide both sides of the equation by -5 to solve for x
x=20.6/-5
x=-4.12
