Question

0,3(5-2а)=4,3-0,3(а-4)

Answer 1

15-6a=43-3a+12
-3a=40
A= -40/3
13 1/3

Answer 2

To solve the equation, let's start by simplifying both sides step by step:

0.3(5 - 2a) = 4.3 - 0.3(a - 4)

First, distribute the 0.3 on both sides:

0.3 * 5 - 0.3 * 2a = 4.3 - 0.3 * a + 0.3 * 4

1.5 - 0.6a = 4.3 - 0.3a + 1.2

Next, combine like terms:

-0.6a + 1.5 = 4.3 - 0.3a + 1.2

Now, let's simplify further:

-0.6a + 1.5 = 5.5 - 0.3a

To isolate the terms with "a" on one side, let's subtract -0.3a from both sides:

-0.6a + 0.3a + 1.5 = 5.5 - 0.3a + 0.3a

Simplifying:

-0.3a + 1.5 = 5.5

Next, let's subtract 1.5 from both sides:

-0.3a + 1.5 - 1.5 = 5.5 - 1.5

Simplifying:

-0.3a = 4

Finally, to solve for "a," divide both sides by -0.3:

(-0.3a) / -0.3 = 4 / -0.3

Simplifying:

a = -4/0.3

Therefore, the solution to the equation is:

a = -13.33
