What is - 2 (x+4.1) = x+2x+12.3?

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
