Mutiply the bracket by -2
(-2)(2y)=-4y
(-2)(-3)= 6
4y^3-4y+6+y
4y^3-4y+y+6 ( combine like terms)
4y^ 3-3y+6
Answer: 4y^ 3-3y+6
solution:
3x-2y=1 , -9x-6y=-3.
solution system can be represent in (13,0) ( 1 3 , 0 ).
We have to draw the model for 42 divide 7 . In order to draw the model we use below steps.
- Draw 7 boxes to represent 7 groups.
- Assume 42 as the number which represents the total of these 7 groups.
- Put a question mark at the first box.
Attached is the model to represents 42 divide 7 .
In the question mark we should put 6. Hence, when we add 6 to 7 times that will be equal to 42.
