Answer:
When the difference of two numbers is zero, it means that the two numbers are the same.
Therefore, any irrational number substracted by itself will be equal to zero.
Here some examples:
- √8 - √8 = 0
- √1.6 - √1.6 = 0
- π - π = 0
5. the first equation gives you the value of y. So plug in the value of y into the second equation:
3x+2(-x-7)=3.
Simplify: 3x-2x-14=3.
Subtract: 1x-14=3.
Add 14 to both sides: x=17.
Now you know the x value.
You plug in the x value into the first equation: y=-17-7
Solve: y=-24
Answer: 17, -24
