Question

How do you solve for Y=-9x-4 Y=5x+10 ?

Answer 1

Answer: {y,x} = {-1,1}

Step-by-step explanation:

Solve equation for the variable  y

     y = -5x + 4

this in for variable  y  in equation

   (-5x+4) - 9x = -10

      - 14x = -14

Solve equation or the variable  x

      14x = 14

  x = 1

By now we know this much :

   y = -5x+4

   x = 1

Use the  x  value to solve for  y

   y = -5(1)+4 = -1
