Question

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

3x − 6y = 3
7x − 5y = −11

a. −2

b. −3

c. x can be any number as there are infinitely many solutions to the system.

d. There is no x value as there is no solution to the system

Answer 1

So we'll solve this problem using substitution. We are going to isolate x in the first equation okay. Once we do that
3x-6y=3 [Add 6y to both sides]
3x=6y+3 [Divide both sides by 3]
x=2y+1.5 Now we put this into the 2nd equation and solve for y
7(2y+1.5)-5y=-11 Now you can solve the problem :)
G2g now so yeah :(
