Answer:
2 x minus 3 y = 12
Negative 4 (2 x minus 3 y) = negative 4 (12)
Step-by-step explanation:
y = two-thirds x minus 4
y = (⅔)x - 4
Multiply the entire equation by 3
3y = 2x - 12
2x - 3y = 12
Multiply both sides by -4
-4(2x - 3y) = -4(12)
If you would like to calculate 5/7 - 2/5, you can do this using the following steps:
5/7 - 2/5 = 25/35 - 14/35 = (25 - 14) / 35 = 11/35
The correct result would be 11/35.

Y=mx+b
m= slope
b=y intercept
From unit conversion, it is found the following results:
6km ≈ 3.73 mi
2.5 L≈ 0.66 gal
90 lb ≈ 40.82 kg

Unit Conversion</h3>
Units of measurement are part of our daily lives. There are different units for area, length, volume, mass, and others. Because of this, it is important to know converting them.
For solving this question you need some information as:
1 km = 0.621371 mi ( unit for length and distance)
1 L = 0.2641722 gallons (unit for volume)
1 lb = 0.453592 kg (unit for mass)
Therefore,
- If 1 km = 0.621371 mi, you will have:
1 km -------- 0.621371 mi
6 km -------- x mi
x= 6* 0.621371
x=3.73 mi
Thus, 6km ≈ 3.73 mi.
- If 1 L = 0.2641722 gallons, you will have:
- 1 L-------- 0.2647122 gal
- 2.5L -------- x gal
- x= 2.5* 0.2647122
- x=0.66 gal
- Thus,
- 2.5 L≈ 0.66 gal.
- If 1 lb = 0.453592 kg, you will have:
- 1 lb-------- 0.453592 kg
- 90 lb -------- x kg
- x= 90* 0.453592
- x=40.82 kg
- Thus,
- 90 lb≈ 40.82 kg
