Answer 1

Answer:

Infinite Solutions

Explanation:

y=165−0.4(x−10);y=165−0.4(x−10)

Rewrite equations:

y=−0.4x+169;y=−0.4x+169

Step: Solve y=−0.4x+169for y:

y=−0.4x+169

Step: Substitute−0.4x+169 for y in y=−0.4x+169:

y=−0.4x+169

−0.4x+169=−0.4x+169

−0.4x+169+0.4x=−0.4x+169+0.4x(Add 0.4x to both sides)

169=169

169+−169=169+−169(Add -169 to both sides)

0=0

Therefore equation has infinite solutions
