There are 3 ways of solving a simultaneous problem, substitution method, elimination method and Gauss-Jordan method. I'm gonna use the substitution method since it's easier and i think it would suit your level more.
First let's try solving for y since it's easier to start with.
Firstly we have to find an equation for x:
Great, now we can use the substitution method to find the value of y using the first equation:
Now we know that y=1 we can solve the first equation we made:
And the answer is 
Double check:
And that's our final answer! (4,1)
Hi there!
We know that the snail lives 1 x 1/2 feet in 3 x 3/4 hours. First you have to simplify or solve the expressions. 1 x 1/2 is equal to 1/2 and 3 x 3/4 is 9/4 or 2.25 in decimal form.
You need to divide 2.25 by 1/2 or 0.5 which is 4.5.
So the snail moves 4.5 or 9/2 feet per hour.
Hope this helps !
Answer:
y = -7
Step-by-step explanation:
Put x = 2 in any one of the equation
5x +2y = -4
5*2 + 2y = -4
10 +2y = -4
2y = -4 -10
2y = -14
y = -14/2
y = -7
The answer is that the first one is not the longer one the second one is.
the first one equals 2
the second one equals 5
