Question

-(5 3/2-1,6)-х=6 3/1 решите пж

Answer 1

15/0,4-х=18/1
37,5-x=18
x=37,5-18
x=189, 5

Answer 2

To solve the equation, let's simplify the given expression first:

-(5 3/2 - 1.6) - x = 6 3/1

First, convert the mixed numbers into improper fractions:

-(5 3/2 - 1.6) - x = 6 3/1

-(11/2 - 8/5) - x = 6 3/1

Now, find a common denominator for 2 and 5, which is 10:

-(55/10 - 16/10) - x = 6 3/1

Simplify the fractions:

-(39/10) - x = 6 3/1

Next, convert the mixed number 6 3/1 into an improper fraction:

-(39/10) - x = 6 3/1

6 3/1 is equivalent to 6 + 3 = 9:

-(39/10) - x = 9

Now, let's solve for x. To do that, isolate x by moving the other terms to the other side of the equation:

-(39/10) + x = -9

To simplify further, we can add the fractions:

x - 39/10 = -9

To eliminate the fraction, multiply the equation by 10:

10x - 39 = -90

Now, solve for x:

10x = -90 + 39

10x = -51

x = -51/10

Therefore, the solution to the equation is x = -51/10.
