Well if you're wanting to use substitution, you first have to end up with one term on either side of the equation. Use the second one as it's easiest.
So: x-2y=11, so find -2y as there is a -2y in the first equation.
then that becomes -2y=11-x. then sub that into equation 1, and you get:
-x+11-x=-13, which equals to -2x+11=-13, which is -2x=-24, so therefore
x=12. then chuck the x into any of the equations to find what y equals.
hope this helps!
Answer:
This system has one answer.
Step-by-step explanation:
This system only has one answer which are: x=1 y=2
Hope this helped! :)
AB = BC
3x-4=5x-10
-4=2x-10
6=2x
3=x
AB = 3x-4
AB = 3 (3)-4
AB = 9-4
AB =5
Therefore, AB is 5.
BC = 5x-10
BC = 5(3)-10
BC = 15-10
BC= 5
The answer tou your question is 8 more hours
green pepper, onion, tomato
= 2x, 5x, 9x
Number of cups = 96
therefore 2x + 5x + 9x = 96
16x=96
x= 96÷16 = 6
Onion = 5x
therefore answer = 6 x 5 = 30
C. 30 is the correct answer :)
