Question

2,8×(0,5a+4)-1,5 (a-6)=

Answer 1

1,4а + 11,2 -1,5а + 9 = -0,1а + 20,2

Answer 2

To solve the equation, let's perform the necessary calculations step by step:

1. Distribute the multiplication: 2.8 × (0.5a + 4) = 1.4a + 11.2

2. Distribute the multiplication on the second term: -1.5(a - 6) = -1.5a + 9

Now, we can rewrite the original equation with the simplified terms:

1.4a + 11.2 - 1.5a + 9 = 0

Combine like terms:

(1.4a - 1.5a) + (11.2 + 9) = 0

-0.1a + 20.2 = 0

To isolate 'a,' subtract 20.2 from both sides:

-0.1a = -20.2

Now, divide both sides by -0.1 to solve for 'a':

a = -20.2 / -0.1

a = 202

So, the solution to the equation is a = 202.
