1) Question 3 The system y = 3.5x - 3.5 y = -3.5x +3.5 has one solution. To find it, you can add the two equations: 2y = 0 => y =0 Now replace that value in any of the two original equations. Doing it with the first of the equations: => 3.5x - 3.5 = 0=> 3.5x = 3.5 = x = 3.5 / 3.5 = 1 Solution (1,0) Answer: one solution. 2) Question 4 <span>The graph of a system of equations will intersect at more than 1 point. Some times: For example: y = x + 2 2y = 2x + 4 Intersects in infinite points. y = x + 2 y = x + 3 will not intersect y = 2x y = x+1 will intersect at one point. And a system with a quadratic equation and a linear equation may drive to intersection in two points. </span>

this is the answer, its pretty simple. I'm not sure the mathematical procedures but if you plug in 7 you get 49. Then all you got to do is subtract by 7, because the question states the number is the same. So basically,
