Question

3x + 2y = 47 and 2x + 3y = 53 ​

Answer 1

Answer:

hi good morning how are you

Step-by-step explanation:

3x + 2y = 47 and 2x + 3y = 53 3x + 2y = 47 and 2x + 3y = 53 3x + 2y = 47 and 2x + 3y = 53 3x + 2y = 47 and 2x + 3y = 53 3x + 2y = 47 and 2x + 3y = 53

Answer 2

Answer:

[1] 2x + 3y = 47

[2] 3x + 2y = 48

Graphic Representation of the Equations :

3y + 2x = 47 2y + 3x = 48

Solve by Substitution :

// Solve equation [2] for the variable y

[2] 2y = -3x + 48

[2] y = -3x/2 + 24

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

[1] 2x + 3•(-3x/2+24) = 47

[1] -5x/2 = -25

[1] -5x = -50

// Solve equation [1] for the variable x

[1] 5x = 50

[1] x = 10

// By now we know this much :

x = 10

y = -3x/2+24

// Use the x value to solve for y

y = -(3/2)(10)+24 = 9
