If x+y=12and x-y=8, what is the value of 2x-xy?

Mathematics

slamgirl [31]3 years ago
8 0

Answer:

2x - xy = 0

Step-by-step explanation:

We need to solve the equations simultaneously to find the values of x and y:

x + y = 12

x - y = 8 - we need to add the equations together

2x = 20

x = 10

Then we substitute x into one of the equations to find y:

10 + y = 12

12 - 10 = y

y = 2

Now we substitute x and y into the final expression:

2(10) - 2(10)

20 - 20 = 0

What is the solution to the inequality 5x - 11 ≥ 31
Molodets [167]
1

 

Add 1111 to both sides

5x\ge 31+115x≥31+11


2

 

Simplify 31+1131+11 to 4242

5x\ge 425x≥42


3

 

Divide both sides by 55

x\ge \frac{42}{5}x≥​5​​42​​
