Question

5(y + 1,2)= 12,5y 4(3-2x) + 24 = 2(3 + 2x)

Answer 1

1. 5y+ 6 =12,5y
5y-12,5y=-6
-7,5y=-6
y=0,8
2. 12-8x +24=6+4x
36-8x=6+4x
-8x-4x= 6-36
-12x=-30
x=2,5

Answer 2

Let's solve the equations step by step:

1. 5(y + 1.2) = 12.5y

   First, distribute the 5 on the left side of the equation:

   5y + 6 = 12.5y

   Now, let's isolate the variable y by moving all terms involving y to one side of the equation and constants to the other side:

   5y - 12.5y = -6

   Combine like terms:

   -7.5y = -6

   Now, divide both sides by -7.5 to solve for y:

   y = -6 / -7.5

   y = 0.8

2. 4(3 - 2x) + 24 = 2(3 + 2x)

   First, distribute the constants on both sides:

   12 - 8x + 24 = 6 + 4x

   Now, let's isolate the variable x by moving all terms involving x to one side of the equation and constants to the other side:

   -8x - 4x = 6 - 12 - 24

   Combine like terms:

   -12x = -30

   Now, divide both sides by -12 to solve for x:

   x = (-30) / (-12)

   x = 5/2 or 2.5

So, the solutions to the equations are:

1. y = 0.8
2. x = 2.5
