Question 175139
A number:  {{{x}}}


Three times the number: {{{3x}}}


Three times the number increased by 5:  {{{3x + 5}}}


Nine times the number:  {{{9x}}}


77 decreased by nine times the number:  {{{77 - 9x}}}


So:  {{{3x + 5}}} is the same as {{{77 - 9x}}} which means:  {{{3x + 5 = 77 - 9x}}}


Just solve for {{{x}}}
