Question

Use the substitution method or the elimination method to solve the system:
-(1/9)x + 2/7(y)=-(1/7)
(7/9)x-2y=1

Answer 1

There is no solution. if both equations are solved for y, then the result below is true for both equations:\[y=\frac{1}{18} (7 x-9) \]Both problem expresssions are equations for the same line.
