Question

3,7-(x:2+1,5)=0,8 решите пж ​

Answer 1

Ответ:

Пошаговое объяснение:

3,7-(x:2+1,5)=0,8

x:2+1,5=0,8-3,7

x:2+1,5= -2,9

х:2= -2,9-1,5

х:2=-4,4

х= -4,4*2

х= -8,8

Answer 2

To solve this equation, we need to isolate the variable x on one side of the equation. Here's how to do it step by step:

1. Start by simplifying the expression on the left side of the equation:

3,7 - (x:2 + 1,5) = 0,8

First, let's simplify the parentheses by dividing x by 2 and adding 1.5:

3,7 - (x/2 + 1,5) = 0,8

2. Remove the parentheses by distributing the negative sign:

3,7 - x/2 - 1,5 = 0,8

3. Combine the constant terms on the left side of the equation:

2,2 - x/2 = 0,8

4. To isolate x, we need to get rid of the fraction by multiplying both sides of the equation by 2:

2*(2,2 - x/2) = 2*0,8

4,4 - x = 1,6

5. Finally, solve for x by subtracting 4.4 from both sides of the equation:

x = 4,4 - 1,6

x = 2,8

Therefore, the solution to the equation is x = 2.8.
