Question

-6*(0,6a-4)+2*(0,4-5)=14

Answer 1

-6×(0,6a-4)+2×(0,4-5)=14

-3,6a+24+2×(-4.6) =14

-3,6a+24-9,2=14

-3,6a+14,8=14

-3,6a=14-14,8

-3,6a=-0,8

a=2/9

Answer 2

Let's solve the equation step by step:

-6*(0.6a - 4) + 2*(0.4 - 5) = 14

First, let's simplify the expressions inside the parentheses:

-6 * 0.6a = -3.6a -6 * (-4) = 24 2 * 0.4 = 0.8 2 * (-5) = -10

Now, the equation becomes:

-3.6a + 24 + 0.8 - 10 = 14

Next, combine the constant terms:

(24 + 0.8 - 10) = 14.8 - 10 = 4.8

The equation is now:

-3.6a + 4.8 = 14

Now, to isolate the variable 'a', we need to get rid of the constant term on the left side. Subtract 4.8 from both sides:

-3.6a + 4.8 - 4.8 = 14 - 4.8

This simplifies to:

-3.6a = 9.2

Now, to solve for 'a', divide both sides by -3.6:

a = 9.2 / -3.6

a ≈ -2.5556

So, the solution for 'a' in the equation is approximately -2.5556.
