Will mark Brainlest please answer. find the value of a, b.
,p, q from the equal order pairs​

Step-by-step explanation:

by order pair we obtain:

cancel 2p from the i equation to get a certain value of p:

now substitute the value of p to the second equation:

simplify parentheses:

cancel 1 from both sides:

divide both sides by 2:

by order pair we obtain:

cancel out y from the second equation:

substitute the value of x to the first equation:

simplify:

divide both sides by 3:

substitute the value of y to the second equation which yields:

by order pair we obtain;

rearrange:

subtract and simplify

substitute the value of q to the first equation:

make q the subject of the equation:

hence,

$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
