simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13

to find this first take note the house cost is $179,000 and the rate for his area is 2.3%

now turn the fraction 2.3% into a decimal, to do so move the . over to the left two times.

.023

now multiply it by 179,000

179,000(.023)= 4117

so he monthly tax payment would be $4417
