1,000,000 is written as 10^6. Other wise it would be too low or too high.
Substitute.
2x+(2x -15) = -3
4x -15 = -3
Add 15 to both sides
4x = 12
Divide by 4
X=3
2(3) + y = -3
6+y=-3
-6 from both sides
Y=-9
(3,-9)
We have to use the Distributive Property in this equation.
By the Distributive Property,

becomes

Now we need to isolate x. Remember PEMDAS?


Simplify the right side.
