It is y+3y-2y = 2y simplified
Then 3y+1-2y can be simplified to y+1
-4(7x-3y-z)-(-6)(9x-z+2)
9y-3y=6y; 6y+2y=8y; so your answer is 8y
5+y+2y? = 5+3y?
3y - 3 = 2y + 5 3y - 2y = 5 + 3 y = 8
It is y+3y-2y = 2y simplified
X + 3y - 2y + 3y = X + (3-2+3)y = X + 4y
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6
Then 3y+1-2y can be simplified to y+1
-3y + y = -2y
5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
-4(7x-3y-z)-(-6)(9x-z+2)
9y-3y=6y; 6y+2y=8y; so your answer is 8y
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.
(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y
