Answer 2

`x=-(27)/(16)\\\\x =- 1(11)/(16)`

Explanation:

`(20x + 18) = 4x - 9\\\\20x+18=4x-9\\\\\mathrm{Subtract\:}18\mathrm{\:from\:both\:sides}\\\\20x+18-18=4x-9-18\\\\Simplify\\\\20x=4x-27\\\\\mathrm{Subtract\:}4x\mathrm{\:from\:both\:sides}\\20x-4x=4x-27-4x\\\\Simplify\\16x=-27\\\\\mathrm{Divide\:both\:sides\:by\:}16\\(16x)/(16)=(-27)/(16)\\\\Simplify\\x=-(27)/(16)\\\\x =- 1(11)/(16)`
