Question 536877
I'll do the first one to get you started.



{{{-8x-45=2-15x}}} Start with the given equation.



{{{-8x=2-15x+45}}} Add {{{45}}} to both sides.



{{{-8x+15x=2+45}}} Add {{{15x}}} to both sides.



{{{7x=2+45}}} Combine like terms on the left side.



{{{7x=47}}} Combine like terms on the right side.



{{{x=(47)/(7)}}} Divide both sides by {{{7}}} to isolate {{{x}}}.



----------------------------------------------------------------------


Answer:


So the solution is {{{x=47/7}}}
