Answer:
The variable is z
Step-by-step explanation:
x should equal -2 and y should equal -3 to solve this i multiplied the first equation by 2 then got rid of the 4y and -4y then i added the 14x to the 9 equaling 23x and added the -40 to the -6 which became 23x=-46 i solved this getting -s for x, then i plugged that into the equations to get y which was -3
We want something that equals 19 right? Anything can work here such as
10+9=19 <---we have our outcome as 19
If you want something more complex
<span>1(10)+10-1=?
</span>When you solve that it equals 19! :)
Commutative property of multiplication is just mixing up the order but the answer stays the same.
Examples: 4 + 5 + 6 = 6 + 4 + 5 ; (a)(d) = (d)(a) ;
Answer:
(-16)(y) or/and (y)(-16)
