4x-6y = 12
Add 6y to both sides
4x = 12 + 6y
Subtract 12 on both sides
4x - 12 = 6y
Divide 6 on both sides
y = 2/3 x - 2
Next equation
-2x + 3y = -6
Add 2x to both sides
3y = 2x - 6
Divide 3 on both sides
y = 2/3x - 2
Answer:
y = .25x
Step-by-step explanation:
In equations, percentages will most often have to be represented with a decimal equivalency. If .75 of the work is done, then 75% of the work has been done. The .75 means 75% of the work has been done.
Percentages are based on 100%; you cannot have more than 100% of something. If 75% (.75) of the work has been done, then 25% (.25) remains. Therefore, the equation that represents the percentae of work that remains is
y = .25x
