Answer:
-5
Step-by-step explanation:
There is different ways to solve methods of elimination but if you wanted to cancel y out you would multiply by the opposite sign....for example
7x + 5y = 19
-5 (2x + y = 19) ---> -10x -5y = 95
this would cancel out your y to solve for x so you can plug it back in and solve! hope this helps!!!

Answer:
I simply listed the factors of 24, and tested which ones worked in this equation: P = 2a + 2b.
So the factors listed were:
24 x 1
12 x 2
8 x 3
6 x 4
After testing each one of these, 6 and 4 had worked for me.
P = 2(6) + 2(4)
P = 12 + 8
P = 20
Therefore, the dimensions of this rectangle are 6 and 4.
