-x + 2y = 6

6y = x + 18


Let's rewrite these equations.


-x + 2y = 6

6y - x = 18


If we multiply the second equation by -1 we can add both of them.


-x + 2y = 6

-6y + x = -18


Add:


-x + (-6y) + 2y + x = 6 + (-18)

2y - 6y + x - x = 6 - 18

-4y = -12

y = -12/-4

y = 3


Substitute y in the equation:


-x + 2y = 6

-x + 2.3 = 6

-x + 6 = 6

-x = 6 - 6

-x = 0

x = 0


Option B.

Write an expression that can be used to multiply 6 x 198 mentally? please answer thanks!
valkas [14]
-6 x 2 + 6 x 200. Since you want to find out 6 multiplied by 198 the easiest way (for me) would be to round it and then substract 12 since 200-198 is equal to 2 and 6 x 2 is equal to 12
