12 x 12 = 144
20 x 12 = 240
=384
ANSWER: 384
<span>A) 2x - 4y = 10
B) 7x - 9y = 12
Multiplying equation A by -3.5
A) -7x +14y = -35 then adding B
B) </span><span><span>7x - 9y = 12</span>
5y = -23
y = -4.6
</span>
2x -4*-4.6 = 10
2x + 18.4 = 10
2x = -8.4
x = -4.2
It has one solution (-4.2, -4.6)
Can you translate by any chance to help you better
Two or more than a number is 2>_x or x<_2.

1. True.
2. False.
3. False.
4. True.
Let me know if those are right. :)
