Question 579073
If you take equation 1, which is x=y+7, and solve for y, you'll get


x=y+7


0 = y+7 - x


-y = 7 - x


y = -7 + x


y = x - 7



Now compare this with equation 2) y = x+7


The slopes are equal to 1, but the y-intercepts are different. 


This suggests that the two lines are parallel and will never cross or intersect each other. 


So this is an inconsistent system. 


Therefore, there are <font color="red">no solutions</font>.
