Explanation:
This is a self-answering question: you solve it by graphing the equations.
<em>The solution is where the lines intersect</em>. The point of intersection of the lines is the point that satisfies all the equations for the lines, hence is a solution to the system. If they do not intersect, there are no solutions. If the lines are coincident, there are an infinite number of solutions.

The equations can be graphed by any of a number of methods. (My favorite is to let a graphing calculator do it.) The method of choice depends on the coefficients and the form the equations are given in. Methods of graphing are a topic for a more lengthy discussion.
-18 +30s -72t +12u is the answer
Answer:
7 = 7 * 10 = 70
Step-by-step explanation:
By intuition, the function of y with respect to x will be:
y = 4x
You can prove this by substitute in each pair of values of x and y
So the constant of relationship is 4
