Answer:
Step-by-step explanation:
Givens
x + y = 2
x - y = 6
Solution
Just add the two equations together. The y's will drop out.
x + y = 2
<u>x - y = 6 </u> Add
2x = 8 Divide by 2
2x/2 = 8/2 Combine
x = 4 Substitute x = 4 into the top equation
x + y = 2
4 + y = 2 Subtract 4 from both sides
4-4+y=2-4 Combine
y = - 2
Answer
x = 4
y = -2
Out of those options centimeter because it’s small but not as small as a millimeter is
If you have some thing like x^2 + x + x^3 + x^2 the correct order would be x^3 + x^2 + x^2 + x.
I Think it is atomic mass
