2(x-1)=42
2x-2=42
2x=44
X=22
Im sure this means add because on a number line when you move to the right its adding. And since the amount of units were moving up by is 6 we would add 0+6 which equals 6.
Step-by-step explanation:
-2x - 6xy - 3y + 7x <em>combine like terms</em>
= (-2x + 7x) - 6xy - 3y
= 5x - 6xy - 3y
Answer:
Step-by-step explanation:
Using elimination means you either add the two equations together or subtract them. You can first multiply the second equation by 2, so you get 4x - 6y = 24. Then you add the two equations together to get 9x = 42. Then you solve for x and then you can solve for y.
