Solving special systems
y=x+1
-x+y=3

Plug the first equation into the second

-x + (x + 1) = 3
1 = 3

This is obviously false, so that means the two lines are parallel and have no solution

If we rarrange -x + y = 3, we get
y = x + 3

And the first equation was y = x + 1

You can see that both have the same slope but different y-intercepts, which means that the two lines are parallel and have no solution.

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet

Y= (2x) /5 - 6step by step(2x)/5 - y = 6- y = -2/5 (x - 15)answer: || y = (2( x - 15 )) /5
