Question

(5.1а+1.38)-3.4а = приа=0.6 и при а1.8 помогите пожалуйста

Answer 1

5.1×0.6=3,6
3,6+1,38=4,44
3,4×0,6=2,04
4,44-2,04=2,4


5,1×1,8=9,18
9,18+1,38=10,56
3,4×1,8=6,12
10,56-6,12=4,44

Answer 2

To solve the equation (5.1a + 1.38) - 3.4a = 0.6 + a * 1.8, we can follow these steps:

1. Distribute the multiplication: - 5.1a + 1.38 - 3.4a = 0.6 + 1.8a

2. Combine like terms: - (5.1a - 3.4a) + 1.38 = 0.6 + 1.8a

3. Simplify: - 1.7a + 1.38 = 0.6 + 1.8a

4. Move all terms with 'a' to one side of the equation: - 1.7a - 1.8a = 0.6 - 1.38

5. Combine like terms: - -0.1a = -0.78

6. Solve for 'a' by dividing both sides of the equation by -0.1: - a = (-0.78) / (-0.1) - a = 7.8

Therefore, the solution to the equation (5.1a + 1.38) - 3.4a = 0.6 + a * 1.8 is a = 7.8.
