Question

How many solutions does this system of equations have?

2x - 2y = 8

2x + 3y = 3

Answer 1

one ordered pair

Answer 2

How many solutions does this system of equations have?

2x - 2y = 8=y=x-4
2(x-y)=8
2x-2y-8=0

Answer 3

y=x-4

Answer 4

it only has 1 correct?

Answer 5

It only has 1 solution. You can tell because if you get both equations into slope-intercept form (that is, solve for y in both equations), they each have a different slope. With different slopes, you've only got 1 solution.

Answer 6

2x + 3y = 3=y=12x/3
2x+3y-3=0
x=3n
y=1-2n
y=1/3(3-2x)

Answer 7

the solution is the order pair or point of intersection of the 2 lines...
