Question

y=3x+5 y=3x-10 system of equations

Answer 1

Answer: Solve equation [2] for the variable  y  

 

 [2]    y = 2x - 5

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

  [1]    (2x-5) - 3x = -10

  [1]     - x = -5

// Solve equation [1] for the variable  x  

  [1]    x = 5  

// By now we know this much :

   y = 2x-5

   x = 5

// Use the  x  value to solve for  y  

   y = 2(5)-5 = 5

Step-by-step explanation:[1]    y - 3x = -10

  [2]    y - 2x = -5

  -3x + y = -10        -2x + y = -5  

Answer 2

Answer:

parallel

Step-by-step explanation:

a1= 3, a2= 3

b1= 1, b2= 1

c1= 5 c2= -10

as a1/a2=b1/b2 but not equal to c1/ c2

:•it is a parallel line formation
