What are the steps to solve?

First, distribute the -2 to each value in the parentheses.

-2x + 4 = 10

(The 4 is positive because a negative multiplied by a negative is a positive)

Then, subtract 4 from both sides to get rid of it.

-2x = 6

Divide by -2 to get x by itself

x = -3

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
