Answer 2

To solve the equation -.7*(.6x+.4)+.3(.6*+.4)=0, we can simplify the expression and then solve for the variable x.

First, let's simplify the equation:

-.7*(.6x+.4) + .3(.6*+.4) = 0

Distribute the multiplication:

(-.7 * .6 * x) - (.7 * .4) + (.3 * .6 * x) + (.3 * .4) = 0

Simplify further:

(-.42x - .28) + (.18x + .12) = 0

Combine like terms:

(-.42x + .18x) + (-.28 + .12) = 0

Simplify:

-.24x - .16 = 0

Add .16 to both sides to isolate the term with x:

-.24x = .16

Finally, divide both sides by -.24 to solve for x:

x = .16 / -.24

Calculating this expression, we get:

x ≈ -0.6667

So, the solution to the equation is approximately x = -0.6667.
