Answer:
If the dimension increased by doubled, tripled or quadrupled, then it will be 2x, 3x, or 4x for each dimension.
You can use elimination
7x - 3y = 4
-10x + 3y = 2
Add both equations
-3x = 6, x = -2
Plug in -2 for x in one equation
7(-2) - 3y = 4
-14 - 3y = 4
-3y = 18, y = -6
Solution: x = -2, y = -6
Absolute Zero, also I suggest cropping out your name and teacher for your safety :3 have an amazing day!
Answer:
One.
Step-by-step explanation:
-4x + 6 = 6x - 2
-4x - 6x = -2 - 6
-10x = -8
There's only value of x which, when multiplied by -10 would produce -8.
That value is 0.8.
-10 * 0.8 = -8
No other value can produce the same result.
This means that there's only one solution.
The number you need is 16 all you have to do is work out the problem and try to understand it they are trying to confuse you don't need an equation.
Hope this help!
Have a Great day mate !!
