Answer:

Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -x + 5
// Plug this in for variable y in equation [1]
[1] x - 2•(-x +5) = 8
[1] 3x = 18
// Solve equation [1] for the variable x
[1] 3x = 18
[1] x = 6
// By now we know this much :
x = 6
y = -x+5
// Use the x value to solve for y
y = -(6)+5 = -1
Solution :

Answer:
a=-4 b=-2 c=-1 d=1 e=2
Step-by-step explanation:
Answer:
b = 44
Step-by-step explanation:
b + 90 + 46 = 180 (Supplementary Angles)
b = 180 - 90 - 46
b = 44
Answer:angle DBC is Obtuse, it's more than 90° but less than 180°
