Question

find the value of y
2(3y+4)=5(y+43)​

Answer 1

Answer: 3

Explanation:   [1]    2x + 5y = 43

  [2]    4x - 3y = 47

Graphic Representation of the Equations :

   5y + 2x = 43        -3y + 4x = 47  

 

Solve by Substitution :

// Solve equation [2] for the variable  x  

 [2]    4x = 3y + 47

 [2]    x = 3y/4 + 47/4

// Plug this in for variable  x  in equation [1]

  [1]    2•(3y/4+47/4) + 5y = 43

  [1]    13y/2 = 39/2

  [1]    13y = 39

// Solve equation [1] for the variable  y  

  [1]    13y = 39

  [1]    y = 3

// By now we know this much :

   x = 3y/4+47/4

   y = 3

// Use the  y  value to solve for  x  

   x = (3/4)(3)+47/4 = 14

Solution :

{x,y} = {14,3}

Answer 2

hola mate ..... here is your answer...

6y+8=5y+215

6y-5y=215-8

y=207.
