9y-3y=6y; 6y+2y=8y; so your answer is 8y
10-y=2y+3 10-3=2y+y 7=3y 7/3=y
y = -1
4n + 3y
are you talking about a system of equations where x+3y=-7 -x+2y=-8 if so, then the answer is {2,-3}
3y - 3 = 2y + 5 3y - 2y = 5 + 3 y = 8
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6
9y-3y=6y; 6y+2y=8y; so your answer is 8y
10-y=2y+3 10-3=2y+y 7=3y 7/3=y
If 3y = 12, 2y = 8
y = -1
4n + 3y
are you talking about a system of equations where x+3y=-7 -x+2y=-8 if so, then the answer is {2,-3}
3y + 2y + 4 + 1 = 805y + 5 = 805y = 75y = 15
5 - 2y = 3y - 5 10 = 5y So, y = 2.
