Question

8(6х-7)-17 -(8.8-х)-(4.7+х) решите пж 2

Answer 1

8(6х-7)-17=48х-56-17=48х-73
-(8.8-х)-(4.7+х)=-8.8+х-4.7-х=-13.5

Answer 2

To solve the given expression, let's simplify step by step:

1. Distribute the multiplication: 8(6x - 7) = 48x - 56

2. Simplify the expression within the parentheses: (8.8 - x) = 8.8 - x (4.7 + x) = 4.7 + x

Now, the expression becomes:

48x - 56 - (8.8 - x) - (4.7 + x)

3. Remove the parentheses by distributing the negative sign:

48x - 56 - 8.8 + x - 4.7 - x

4. Combine like terms:

(48x + x - x) - (56 + 8.8 - 4.7)

Simplifying further:

48x - 56 + 0.3

5. Combine the remaining terms:

48x + (0.3 - 56)

6. Finally, simplify the expression:

48x - 55.7

So the final result of the expression is: 48x - 55.7
