Answer:
35
Step-by-step explanation:
y = k*x
21 = k*3
k = 7
x=5 .. y = 7 * 5 = 35
1.75=12.3-x/2.8
x=(12.3-1.75)2.8
x=29.54
Answer:
x=-3, y=1. (-3, 1).
Step-by-step explanation:
-x+5y=8
3x+7y=-2
----------------
3(-x+5y)=3(8)
3x+7y=-2
--------------------
-3x+15y=24
3x+7y=-2
------------------
22y=22
y=22/22
y=1
-x+5(1)=8
-x+5=8
-x=8-5
-x=3
x=-3
