Question

А) 16x +72 = 17+5x Б) 5y-3(6+4y)= -2-(15y-38)

Answer 1

Ответ:

А) 16x+72=17+5x

х=-5

Б) 5y-3(6+4y)=-2-(15y-38)

у=6.75

Пошаговое объяснение:

А) 16x+72=17+5x

16х-5х=17-72

11х=-55

х=-55:11

х=-5

Ответ: -5

Б) 5y-3(6+4y)=-2-(15y-38)

5у-18-12у=-2-15у+38

5у-12у+15у=18-2+38

8у=54

у=54:8

у=6.75

Ответ: 6.75

Answer 2

$A) 16x+72=17+5x\\16x-5x=17-72\\11x=-55\\x=(-55):11\\x=-5\\B)5y-3(6+4y)= -2-(15y-38)\\5y-18-12y=-2-15y+38\\-7y-18=36-15y\\-7y+15y=36+18\\8y=54\\y=54:8\\y=6,75$

Answer 3

Sure, I can help you solve these equations.

A) 16x + 72 = 17 + 5x

Let's start by isolating the variable 'x':

1. Subtract 5x from both sides to move the variable terms to one side:

   16x - 5x + 72 = 17

   11x + 72 = 17

2. Next, subtract 72 from both sides to isolate the variable:

   11x = -55

3. Finally, divide both sides by 11:

   x = -5

So, the solution to the first equation is x = -5.

B) 5y - 3(6 + 4y) = -2 - (15y - 38)

Let's simplify and solve for 'y':

1. Distribute the -3 inside the parentheses:

   5y - 18 - 12y = -2 - 15y + 38

   -7y - 18 = -2 - 15y + 38

2. Combine like terms:

   -7y - 18 = -15y + 36

3. Add 15y to both sides to isolate the variable:

   8y - 18 = 36

4. Add 18 to both sides:

   8y = 54

5. Finally, divide both sides by 8:

   y = 6.75

So, the solution to the second equation is y = 6.75.
