Question

8 умножить скобка октрыта 2игрикплюс 1.5скобка закрыта плюс 5.7=4скобка окрыта 2 игрик -8

Answer 1

8(2у+1,5)+5,7=4(2у-8)
16у+12+5,7=8у-32
16у-8у=-32-12-5,7
  8у=- 49,7
   у=-6, 2125

Answer 2

8( 2у + 1,5 ) + 5,7 = 4( 2у - 8 )
16у + 12 + 5,7 = 8у - 32
16у - 8у = - 32 - 17,7
8у = - 49,7
у = - 6,2125

Answer 3

To solve this equation, we need to apply the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Following this rule, we first need to simplify the expression inside the parentheses:

2y + 1.5

Next, we need to multiply this expression by 8:

8(2y + 1.5)

Using the distributive property of multiplication, we can expand this expression:

16y + 12

Now we can simplify the expression on the right-hand side of the equation:

4(2y - 8) = 8y - 32

Finally, we can set the two expressions equal to each other and solve for y:

16y + 12 = 8y - 32

8y = -44

y = -5.5

Therefore, the solution to the equation is y = -5.5.
