Question

Solve for x. 7(x - 3) = 4(x + 5) x =1/11 x =1/3 x =41/11 x =41/3

Answer 1

To solve for the x, distribute first the numerical coefficients to the terms on the parentheses. This becomes,
   
                                          7x - 21 = 4x + 20

Transpose all the terms with x and the constant on either sides of the equation,
 
                                           7x - 4x = 20 + 21
  
                                        3x = 41   ;    x = 41 / 3

Thus, the answer is x = 41/3 which is fourth among the choices.
