9y-3y=6y; 6y+2y=8y; so your answer is 8y
6y=5y+2y 6y=7y that does't work its unequal -
(3, 3)
x = -4 and y = 4
6y + (2-2)y = 6y 6(5) + (2-2)5 = 6(5) 30 + 0 = 30
9y-3y=6y; 6y+2y=8y; so your answer is 8y
-6y + 14 + 4y = 32-2y = 32 - 14-2y = 18y = - 9
6y=5y+2y 6y=7y that does't work its unequal -
(2, 1)
(3, 3)
x = -8, y = 10
(3,3)
x=6y-4x=-2y+28Substitute (6y-4) for x in the second equation and solve for y:6y-4=-2y+288y=32y=4Then solve for x:x=6(4)-4=20(20,4)
x = -4 and y = 4
6y + (2-2)y = 6y 6(5) + (2-2)5 = 6(5) 30 + 0 = 30
10y = 2y - 6y + 7 10y =-4y + 7 10y +4y = 7 14y = 7 y = 1/2 = .5
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.
