SOLUTION: solve by substitution y=2x+1 the second part is 3x+y=11, I know that the formula for x is 3x+(2x+1)=11, that then becomes 5x+1=11 subtract 1 from both sides and you get 5x=10 which

Question 1030464: solve by substitution y=2x+1 the second part is 3x+y=11, I know that the formula for x is 3x+(2x+1)=11, that then becomes 5x+1=11 subtract 1 from both sides and you get 5x=10 which comes out to x=2 so the x coordinate is 2 i don't know how to find the y coordinate

x=2
Now put back into either part
y=2x+1
y=2(2)+1=5
check with the other equation (2,5): 3(2)+5=11
(2,5) is the answer.
