Answer:
x=3 y = 4
Step-by-step explanation:
3x+5y=29 .........*2 (multiply by2) = 6x+10y=58
2x+3y=18 *-3 = (multiply by -3)= -6x-9y = -54
ADD both(-6x cancels 6x) y= 4
2x+ 3y = 18 2x+ 12 = 18 2x = 6 x = 3
2/3
(6 -4) / (2 - (-1)) =(2) / (2+1) = 2/3
the answer would be .5 miles
answer = 21
2n - 2 = 40
2n - 2 + 2 = 40 + 2
2n = 42
2n/2 = 42/2
n = 21
