Question

2x + y = 15 x = 15 - 2y is it no solution?

Answer 1

Answer:

It has a solution.

Step-by-step explanation:

Step 1: Rearrange 1st equation into slope-intercept form

2x + y = 15

y = 15 - 2x

Step 2: Rearrange 2nd equation into slope-intercept form

x = 15 - 2y

2y + x = 15

2y = 15 - x

y = 15/2 - x/2

Step 3: Rewrite systems of equations

y = 15 - 2x

y = 15/2 - x/2

Since the two lines are not parallel, they will have a solution.
