Answer:

x=4 and y=1

Explanation:

Let's solve your system by substitution.

2x+3y=11;y=x−3

Rewrite equations:

y=x−3;2x+3y=11

Step: Solve y=x−3 for y:

y=x−3

Step: Substitute x−3 for y in 2x+3y=11:

2x+3y=11

2x+3(x−3)=11

5x−9=11 (Simplify both sides of the equation)

5x−9+9=11+9( Add 9 to both sides)

5x=20

5x/5=20/5

(Divide both sides by 5)

x=4

Step: Substitute 4 for x in y=x−3:

y=x−3

y=4−3

y=1(Simplify both sides of the equation)

Answer:

x=4 and y=1

List and explain the factors to consider when buying a computer
PSYCHO15rus [73]

Answer:

what it's main use is going to be

Explanation:

The main factor when considering buying a PC is what it's main use is going to be. This will determine what components you will need to look for. For example, if you are going to use the computer for video editing and work then you will need one with a high end CPU and lots of RAM. If you are going to use the PC for regular everyday use such as work programs (AutoCAD, Office, Photoshop, etc. ) Then you can buy a regular office computer with a mid-tier CPU, and 8GB of RAM, and no graphic card. A PC for gaming at high resolutions will require all high end parts including a high end graphics card. Therefore, knowing what its main use will be will determine cost, and what tier components you will need to buy.
