If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to x from the first equation is substituted into the second equation.

x – 2y = 2
x + 3y = 17

Question

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to x from the first equation is substituted into the second equation.

x – 2y = 2
x + 3y = 17

nubeer · Answer

re- arrange your first equation 
x = 2+ 2y ( got this by adding 2y on both sides.) 
now put this value of x in the second equation.

zpupster · Answer

in the first equation add 2y to both sides of equation 
like so:
x-2y +2y = 2+2y
we are trying to get x by itself. 
we will have 
x=2y+2
substitute this  for the x in 2nd equation

nubeer · Answer

you will get
 2+2y +3y =17
now solve it for y
