Question

What is the value of the x variable in the solution to the following system of equations?

3x − 6y = 3
7x − 5y = −11

Answer 1

3x − 6y = 3
7x − 5y = −11
-----------------------
3x = 3+ 6y
x = (3+ 6y)/3
--------------------
7x − 5y = −11
7 (3+ 6y)/3 − 5y = −11

(21)(1+2y)/3-5y=-11

7(1+2y)-5y=-11

7+14y-5y=-11

7+9y=-11

9y=-18

y=-2
------------------
x = (3+ 6y)/3

x=(3+6(-2))/(3)

x=(3-12)/(3)

x=(-9)/(3)

x=-3

Answer 2

X=-3
