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
The expression 3y + 2y + y simplifies to 6y. This is because when you add like terms (terms with the same variable, in this case y), you add the coefficients (numbers in front of the variable) together. In this case, 3y + 2y = 5y, and then adding another y gives you 6y.
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
