-5 because the denominator can’t equal zero
X^2 -36 = 0 the ans is X=6 and x =-6 because 6^2=36
Answer:
x=-1
y=4
z=7
Step-by-step explanation:
3x + y - z= -6(1)
2x - y + 2z = 8(2)
4x + y - 3z = -21(3)
(1)+(2): 5x+z=2(4)
(2)+(3): 6x-z=-13(5)
(4)+(5): 11x=-11
x=-1
so z=2-5x=7
y=-6-3x+z=4
Answer: 3. 55° 2. 225° 1. 125°
Step-by-step explanation: don't want brainliest
it would be 13/12 because 2/12+8/12+3/12= 13/12
