2 * AB = AC
2 * 8v = 2v + 42
16v - 2v = 42
14v = 42
v = 42/14
v = 3
BC = AB = 8v = 8*3 = 24
Answer:
x= -3
y= -5
Step-by-step explanation:
10y - 3x = -41
+
-5y + 3x = 16
10y + (-5y) = 5y
-3x + 3x = 0
-41 + 16 = -25
5y + 0 = -25
y = -25/5
y= -5
10y -3× = -41
(10×-5) - 3x = -41
- 3x = - 41 + 50
- 3x = 9
x = -3
The answer is that y is equal to -3 and x is equal to 7
2x-y=17
-2(x-y)=10 )
--------------
2x-y=17
-2x+2y=-20
----------------
y=-3
x-y=10
x-(-3)=10
x+3=10
-3 -3
----------
x=7
