Answer:

-3.21538461538

Explanation:


\mathrm{Equation\;Given:}\; 5+5x=(12x-(12)/(5)\cdot \:7)/(5)


\mathrm{Multiply\;both\;sides\;by\;5}:
5\cdot \:5+5x\cdot \:5=(12x-(12)/(5)\cdot \:7)/(5)\cdot \:5


\mathrm{Now\;we\;have\;}:
25+25x=12x-(84)/(5)


\mathrm{Subtract\;by\;sides\;by\;25}:
25+25x-25=12x-(84)/(5)-25


\mathrm{Thus\;we\;have}:
25x=12x-(209)/(5)


\mathrm{Subtracting\;12x\;from\;both\;sides}:
25x-12x=12x-(209)/(5)-12x


\mathrm{So\;then\;we\;have:}
13x=-(209)/(5)


\mathrm{Now\;divide\;both\;sides\;by\;13}:
(13x)/(13)=(-(209)/(5))/(13)


\mathrm{Hence\;we\;have}:\;\;x=-(209)/(65)


\mathrm{Decimal\;form}:-3.21538461538
