-3x-3y=3
5x+y=-17
Substitution
What does x and what does y equal

Step-by-step explanation:

Given Equations:

     Equation:1

     Equation:2

Solving Equation:2 for the value of 'y'

Subtracting '5x' both sides:

 Equation:3

Using substitution method:    Put the value of 'y' in equation:1

Subtracting '51' both sides:

Putting the value of 'x' in equation:3

The values of 'x' and 'y' are:

Step-by-step explanation:

-3x - 3y = 3 (i)

5x + y = -17

       y = -5x - 17

Substitue y value in equation (i)

-3x - 3*(-5x - 17) = 3

-3x -3*(-5x) -3*(-17) =3

-3x + 15x + 51 = 3

12x + 51 = 3

12x = 3 - 51

12x = -48

x = -48/12

x =-4

Sustitute x value in Equation (i)

-3*(-4) - 3y = 3

12 - 3y = 3

-3y = 3 -12

-3y = -9

y =-9/-3

y = 3
