Which is the most efficient way to solve this equation?
X + 7 = 12

○Subtract 12 from both sides of the equation so all terms will
be on the same side of the equal sign.
○Add -7 to both sides because that will result in an equivalent
equation with x alone on one side
○Nothing, because the equation is already solved
○Add 7 to 12 because x equals 19.

subtracting 7 from 12

Step-by-step explanation:

That would be most efficient. Subtracting seven from twelve will quickly give you your value of x without moving the x itself. And there's no negatives

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
