Answer: x = 1, y = - 5
Step-by-step explanation:
The given system of linear equations is expressed as
x - 2y = 11- - - - - - - - - - - - -1
- x + 6y = - 31- - - - - - - - - - - -2
We would eliminate x by adding equation 1 to equation 2. It becomes
- 2y + 6y = 11 - 31
4y = - 20
Dividing the the left hand side and the right hand side of the equation by 4, it becomes
4y/4 = - 20/4
y = - 5
Substituting y = - 5 into equation 1, it becomes
x - 2 × - 5 = 11
x + 10 = 11
Subtracting 10 from the left hand side and the right hand side of the equation, it becomes
x + 10 - 10 = 11 - 10
x = 1
Answer:
Step-by-step explanation:
Given:
Number line is from range -2 to 2 with all increment of ±
on both sides.
Step 1: First we will solve the equation we will get;
Step 2: Now we will try to make the denominator common so we will get;
Step 3: Now from the number line when we subtract 
from 
we get number of spaces left are - 7
Hence now it will become:
Hence the final Answer is
