5x-2=3x+8
X=5
That's your answer
B is the correct answer not totally sure tho hope this helps
8x+3y=9
-8x. -8x
3y = -8x+9
3y/3 = (-8x+9)/3
y = -8/3x +3
so, slope is -8/3
EXPLANATION:
Let the smaller no. be x.
Therefore, The bigger no. = x+12
x + 12 + x = 84
=> 2x = 84-12
=> x = 72/2
=> x = 36
ANSWER: The two numbers are (36+12) 48 & 36
Hope it helps u!
