Assuming the system has equations
Then we can examine the gradients to make our choice without necessarily solving the equations.
Interestingly, both equations are in slope-intercept form. (y=mx+c) where m=3 is the slope of the first equation and m=2 is the slope of the second equation.
Since the slopes are not the same the lines are not parallel.
Non-parallel lines in the same plane will meet at only one point, there is only one solution.
The system is consistent because there exist a solution.
6 square meters
3 times 2 equals 6 so 6 square meters.

(8, - 1 )
One way is as follows
Given the 2 equations
x - 2y = 10 → (1)
x + 3y = 5 → (2)
Subtracting (2) from (1) term by term will eliminate the x- term
(x - x) + (- 2y - 3y) = (10 - 5), that is
- 5y = 5 ( divide both sides by - 5 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting y = - 1 into (2)
x + 3(- 1) = 5, that is
x - 3 = 5 ( add 3 to both sides )
x = 8
Solution is (8, - 1 )
x = ± 4
x² = 96 ( take the square root of both sides )
x = ± = ± = × = ± 4
Elizabeth wins, Erin wins and Anna wins is the order from least likely to most likely.
It is a branch of mathematics that deals with the occurrence of a random event.
Erin, Elizabeth, and Anna are playing a game.
The probability of winning the game are:
P(Erin wins) = 0.3
P(Anna wins) = 1/2
P(Elizabeth wins) = 20%
Let us convert all to the decimal values.
P(Erin wins) = 0.3
P(Anna wins) = 1/2=0.5
P(Elizabeth wins) = 20%=20/100=0.2
The ascending order of these will be 0.2,0.3,0.5.
The likely event will have a probability one.
least likely to most likely.
So, Elizabeth wins, Erin wins and Anna wins is the order from least likely to most likely.
