Firstly we are looking for two variables x,y so that we need two formulas .
the second formula is missing
Hey you're using Apex xD
Answer is D.
Here's an example
6= 3x2
Just divide. 6/2 = 3 <span />
I hope this helps you
Perimeter =2 (width +length )
324=2 (67+length )
162-67=length
length =95
(2x + 3y = 12) x (-2)
(4x - 3y = 6) x 1
-4x - 6y = -24
4x - 3y = 6
You can cancel out the x values by adding the two equations together.
(-4x + 4x) + (-6y - 3y) = (-24 + 6)
-9y = -18
y = 2
Solve for x now...
4x - 3(2) = 6
4x - 6 = 6
4x = 12
x = 3
Check... (x = 3, y = 2)
2(3) + 3(2) = 12
6 + 6 = 12
12 = 12 <- this works!
4(3) - 3(2) = 6
12 - 6 = 6
6 = 6 <- this works!

6
