SOLUTION: I have to solve this problem by substitution: 2x + y = 6 x= 3y + 10 I begin by using the 2(3y + 10)+ y = 6 Multiply: (6y + 20) + y = 6 add 6y + y to get 7y + 20= 6

Question 258079: I have to solve this problem by substitution:
2x + y = 6
x= 3y + 10
I begin by using the 2(3y + 10)+ y = 6
Multiply: (6y + 20) + y = 6
add 6y + y to get 7y + 20= 6
-20= 6 -20
7y = -14
7ydivided by 7 = -14 divided by 7
y = -2
put the -2 for the y x = 3 (-2) + 10
x = -6 + 10
x = 4
so my answer would be
(4,-2)
My answer works out when I check my work. Please confirm that my work is correct.
