Which statement best describes why computer models are useful in science?

The scientific models are constructed on the basis that these models can represent the simplified versions of the complex systems. The computer models are the models which are used on the scientific world to understand the complex system based on the mathematical equations and variables. The best and common use of the computer models is related to climate change as to predict the weather forecasting like tsunamis, earthquakes and many more.

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4
