Answer 2

Answer:

2] 5y = -3x + 19

[2] y = -3x/5 + 19/5

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

[1] 5x - 2•(-3x/5+19/5) = 11

[1] 31x/5 = 93/5

[1] 31x = 93

// Solve equation [1] for the variable x

[1] 31x = 93

[1] x = 3

// By now we know this much :

x = 3

y = -3x/5+19/5

// Use the x value to solve for y

y = -(3/5)(3)+19/5 = 2

Solution :

{x,y} = {3,2}
