the sum of 38 and three times a number is 89

(38+3n) = 89

subtract 38 from each side

3n = 51

divide by 3

n = 17

38+3x=89 is the proper way to write this equation.

<em>Now to solve, first subtract 38 from both sides</em> (38-38 and 89-38)

3x=51

<em>Now divide both sides by 3</em>( 3x/3 and 51/3)

x=17

Answer:

(-3, 1)

The solution is the point at which both lines intersect.

This is the solution since both lines would have that point and only that ppoint in this type of problem. IN a graph where 2 lines are parralel, there is no solution as they never intersect . on a graph where the 2 lines overlap there is infinite solutions. FInally in a graph like this there is exactly one solution and it is the intersection of both lines
