Question

What is the solution of the system of equations?

y = –2x + 5
y = –2x + 20


(0, 20)


(1, 3)


no solution


infinitely many solutions

Answer 1

no solution

Explanation:

Answer 2

Solve for Y: Y = - 2x + 5
Y = - 2x + 20


I will try to solve your system of equation:
Y = - 2x + 5y; = - 2x + 20

Step: Solve y = - 2x + 5 for y


Step:
Substitute - 2x + 5 for y in y = - 2x + 20
y = - 2x + 20
- 2x + 5 + 2x = - 2x + 20 + 2x (add 2x to both sides)

5 = 20
5 + - 5 = 20 + - 5 ( add - 5 to both sides)

0 = 15

As you can see, we obtain a false equation. This means that the system as No Solutions.


Thus your answer is: No Solution
