Make x the subject of the formula
6x + a = 5(x + 1)​

x = 5 - a

Step-by-step explanation:

Given

6x + a = 5(x + 1) ← distribute

6x + a = 5x + 5 ( subtract 5x from both sides )

x + a = 5 ( subtract a from both sides )

x = 5 - a

x=5-a

Step-by-step explanation:

multiplica el paréntesis por 5

6x+a=5x+5

mueva el variable al lado izquierdo y cambie su signo

6x+a-5x=5

mueva el variable al lado derecho y cambie su signo

6x-5x=5-a

agrupe los términos semejantes

x=5-a

escriba la soluciones de x en forma de paréntesis

x=5-a

$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
