Question 744087: I am using substitution to find coordinates for x and y. Problem reads: 2x+3y=25 , where y=3x+1.
I understood that to be 2x+3*(3x+1)=25,
Using distributive property, now I have 2x+9x+1=25.
Simplified that to 11x=24, or x=24/11
My textbook shows the correct final answer for coordinates is x=2, y=7, so I am way off. Can you tell where I went wrong?
