solve the system of linear equations by substitution?

Question

x=17-4y

y=x-2

 

 

x=16-4y

3x+4y=8

 

 

2x=12

x-5y-29

 

Answer 1

2x=12   ... so x = 6; you should be able to see this for yourself!
x-5y-29  ... but here you have mis-typed, there's no equal sign to make it an equation.  Once you fix this equation, replace the x by 6, then you can solve for y.
