Question

Which point is a solution to the system of linear equations? y = −x + 3 x − 3y = 15? (−1, 5) (0, 3) (3, 0) (6, −3) Qu

Answer 1

Explanation:

First we need to change them to slope intercept form.

The first equation is good. The second is not. In slope intercept form it would be y=1/3x-5. And now we solve. -x+3=1/3x-5. -5-3=8. 1/3x+x=4x/3. Rember we have to do opposite operations. Now we have 4x/3=8 Now we isolate x by dviding 8/4=2. We have 3=2. Right here we multiply which is 6. Now we enter 6 as x in the first equation and solve for y. -(6)+3 which is -3. so our solution would be (6,-3)
