We have to determine the conversion factor used to convert inches to yards. Yard and inch are US and British customary length units. We know that 1 yard = 3 feet = 36 inches. So we just have to divide 1 by 36. 1 : 36 = 0.027777.... ( more accurate with more decimal digits ). For example: 54 yards = 54 * 0.0277777 = 1.4999958 ( approx. 1.5 ).

Step-by-step explanation:
23x + 10y = 86
28x + 5y = 76
solve by elimination
multiply the top by -1 and the bottom by 2
-23x + -10y = -86
56x + 10y = 152
add them
33x = 66
x = 2
with x = 2 plug x into one of the equations
23x + 10y = 86
23(2) + 10y = 86
46 + 10y = 86
10y = 40
y = 4
x = 2 and y = 4 so
