Question 118838
twice a number {{{x}}} plus three multiplied by five:

{{{(2x + 3)5}}}

is equal to the product of three times the number minus one, and seven

{{{ (3x - 1) 7}}}

So, we will have


{{{(2x + 3)5 =(3x - 1) 7 }}}

{{{10x + 15 = 21x-7}}}………. move {{{15}}} to the right and {{{21x}}} to the left

{{{10x -21x= -15-7}}}………. 

{{{-11x  = -22}}}……..divide both sides by {{{-1}}}

{{{-11x/-1  =  - 22/-1}}}……..

{{{11x  =  22}}}……..

{{{x  =  22/11}}}……..

{{{x  =   2}}}….

So, your answer is {{{A}}}
