Since the coefficients of x are NOT equal, we can conclude that the system of equations represents two lines with different slopes. Two lines with different slopes will intersect at a single point, meaning they have only one solution.rephrase like a 8th grader
Because the numbers in front of x are different, it means that the lines in the equations have different steepness. When two lines have different steepness, they will meet at one point, which means there is only one solution.
