Пошаговое объяснение:

$\frac{2y+6}{3}-4=\frac{y}{2} +1|*6\\2(2y+6)-4=3y+1\\4y-3y=1-12+4\\y=-7$

Answer 2

It looks like you've provided a set of equations and expressions. Let's go through each of them step by step:

1. Equation 1: (2y + 6) / 3 - 4 = y / 2 + 1

   Let's solve for y in this equation:

   Start by distributing the division and subtraction:

   (2y + 6) / 3 - 4 = y / 2 + 1 (2y + 6) / 3 = y / 2 + 5

   Multiply both sides of the equation by 3 and 2 to get rid of fractions:

   2(2y + 6) = 3(y / 2 + 5) 4y + 12 = 3y + 30

   Subtract 3y from both sides:

   y + 12 = 30

   Subtract 12 from both sides:

   y = 18

2. Equation 2: (y / 7 - 3) * 6 + 64 = 2y - 18

   Let's solve for y in this equation:

   Distribute the multiplication and addition:

   (y / 7 - 3) * 6 + 64 = 2y - 18 6(y / 7) - 18 + 64 = 2y - 18

   Multiply 6/7 by y:

   (6/7)y - 18 + 64 = 2y - 18

   Subtract (6/7)y from both sides:

   -18 + 64 = 2y - (6/7)y - 18 46 = (8/7)y - 18

   Add 18 to both sides:

   64 = (8/7)y

   Multiply both sides by 7/8:

   y = 56/8 y = 7

3. Equation 3: (98 – 4y) / 15.8 = 24y

   Let's solve for y in this equation:

   Multiply both sides of the equation by 15.8 to get rid of the fraction:

   98 - 4y = 15.8 * 24y 98 - 4y = 379.2y

   Add 4y to both sides:

   98 = 383.2y

   Divide both sides by 383.2:

   y = 98 / 383.2

4. Equation 4: (98 – 4y) / 15.8 = 24y

   Let's solve for y in this equation:

   Multiply both sides of the equation by 15.8 to get rid of the fraction:

   (98 – 4y) / 15.8 = 24y 98 - 4y = 15.8 * 24y 98 - 4y = 379.2y

   Add 4y to both sides:

   98 = 383.2y

   Divide both sides by 383.2:

   y = 98 / 383.2

It seems there might be a mistake in the last equation. Both Equations 3 and 4 appear to be the same. Please double-check the equations, or if you have any other questions, feel free to ask!
