Answer: IF you have two equations with the 2 variables, x and y, you can substitute one y-value with the other, then solve.
Step-by-step explanation: For example:
y = 2x + 4
3x+y = 9
We can substitute the value of y from the first equation, 2x + 4, into the second equation. So, the second equaton becomes:
3x + 2x + 4 = 9
Now solve for x:
5x + 4 = 9
5x = 5
x = 1
This value of x then can be used to find y, by substituting in the value "1" for x in the first equation:
y = 2x + 4 = 2(1) + 4 = 2 + 4 = 6
So, the solution to this linear system is (1, 6)
Y=1x+6 or y = x+6
Y=Mx+b
M=1
6=1(0) +b
b= 6
The answer is
Length=6
Width=4
I just guessed and checked here but you might have learned a better way to do it for future problems.
Well I am assuming you want to compare them or something so yeah:
You have to find a common denominator of 4 & 6, so you could multiply them together, this makes 24. Because you have to do the same thing to the top and the bottom, you have to multiply 2/4 (which is now 2/24) by 6, and the 2/6 (which again is 2/24) by 4 which leaves you with 12/24 (2/4) and 8/24 (2/6).
We can simplify these fractions by dividing them, but as you may know 12 is half of 24 so 12/24 would also be 1/2.
If you keep dividing by 2 you will find that 8/24 is also equal to 1/3. This is easier to find out by the beginning number but I mentioned it anyway because I didn't understand what you were asking.
Overall if you noticed when comparing 2/4 and 2/6 we found that Mei Lyn painted more wall than Mario.
