I am assuming it is a system of equations and that you need to find x and y
-x-7y=14 so -x=14+7y, x=-7y-14
-4x-14y=28 substitute x ,
-4(-7y-14)-14y=28,
28y+56-14y=28,
14y=28-56
y= -28/14= -2
<span> x=-7y-14= -7(-2)-14=14-14=0
x=0 and y= -2</span>
Answer:
x + y = 52
y = x + 12
(soccer team) x = 20, (hockey team) y = 32
Step-by-step explanation:
x = students on the soccer team
y = students on the hockey team
x + y = 52
y = x + 12
Substitute y = x +12 to get:
= x + x +12 = 52
= 2x + 12 =52
Isolate x for 2x + 12 = 52: x = 20.
Now incorporate a new equation with x = 20:
y = 20 +12
y = 32
Therefore:
x = 20, y = 32
