Answer: 33/5</h3>
===============================================
Explanation:
Start at 6 and count the small tickmarks to see that it takes 5 spaces to go from 6 to 7 on the number line.
So each small tickmark represents 1/5 of a unit.
The arrow is 3 ticks away from the 6, so we add on 3/5 to 6 getting the mixed number 6 + 3/5 = 6 & 3/5
The 6 is the whole part, while 3/5 is the fractional part.
----------------
Let's convert to an improper fraction
6 & 3/5 = 6 + 3/5
6 & 3/5 = 6*(5/5) + 3/5
6 & 3/5 = 30/5 + 3/5
6 & 3/5 = (30+3)/5
6 & 3/5 = 33/5
----------------
You could also use the formula
a & b/c = (a*c + b)/c
to get
6 & 3/5 = (6*5 + 3)/5
6 & 3/5 = 33/5
Using Substitute method:
Replace y value of equation 2 into equation 1:
4x + (x+6) = 1
Solve for x:
4x + x + 6 = 1
5x = 1 - 6
5x = -5
x = -5/5
x = -1
Pick any of the two equation, replace x with it's value -1 and solve for y:
y = (-1) + 6
y = -1 + 6
y = 5
Solution: (-1, 5)
