Question

X-(9x-10)+11=12x+3(-2x+ 1/3)

Answer 1

x - (9x - 10) + 11 = 12x + 3(-2x +
`(1)/(3)` ) equals x =
`(10)/(7)` .

First, simplify brackets. / Your problem should look like: x - 9x + 10 + 11 = 12x + 3(-2x +
`(1)/(3)` ).
Second, simplify x - 9x + 10 + 11 to -8x + 10 + 11. / Your problem should look like: -8x + 10 + 11 = 12x + 3(-2x +
`(1)/(3)` ).
Third, simplify -8x + 10 + 11 to -8x + 21. / Your problem should look like: -8x + 21 = 12x + 3(-2x +
`(1)/(3)` ).
Fourth, expand. / Your problem should look like: -8x + 21 = 12x - 6x + 1.
Fifth, simplify 12x - 6x + 1 to 6x + 1./ Your problem should look like: -8x + 21 = 6x + 1.
Sixth, add 8x to both sides. / Your problem should look like: 21 = 6x + 1 + 8x.
Seventh, simplify 6x + 1 + 8x to 14x + 1. / Your problem should look like: 21 = 14x + 1.
Eighth, subtract 1 from both sides. / Your problem should look like: 21 - 1 = 14x.
Ninth, simplify 21 - 1 to 20. / Your problem should look like: 20 = 14x.
Tenth, divide both sides by 14. / Your problem should look like:
`(20)/(14)` = x.
Eleventh, simplify
`(20)/(14)` to
`( 10)/(7)` . / Your problem should look like:
`(10)/(7)` = x.
Twelfth, switch sides. / Your problem should look like: x =
`(10)/(7)` which is your answer.
