Question

How many solutions does the system of equations below have? y = 2x – 10 y = 2x – 10 - no solution one solution infinitely many solutions ​

Answer 1

11/2y.....................

Answer 2

11/2y

Explanation:

Let's solve for x.

y=2x−10y

Step 1: Flip the equation.

2x−10y=y

Step 2: Add 10y to both sides.

2x−10y+10y=y+10y

2x=11y

Step 3: Divide both sides by 2.

2x

2

=

11y
