50x = 450
x = 450 / 50
x = 9
It’s 17 because the ranking of the two teams add up to 17
Answer:
z>-4
Step-by-step explanation:
substitution and elimination means that you need to use one equation and substitute it in place of some variable in the other equation.
Consider the above two equations.
Take equation 1, which is 4x-2y=22 => x=(22+2y)/4
substitute the x value gained above in equation 2.
so, 2((22+2y)/4)+4y=6
22+2y+8y=12 => 10y = -10 => y= -1.
Substitute y= -1 in x value obtained in the beginning.
So, x= (22 - 2)/4 => 5.
There fore, x= 5 and y= -1
Hope it helps.
10 - 2x
10 - 2(7)
= 10 - 14
= -4
