Question

6(4x+2)+7(-5x+3)=66 equação

Answer 1

6(4x+2)+7(-5x+3)=66
24X + 12 - 35X + 21 = 66

- 11X = -12 - 21 + 66

-11X = - 33 + 66

-11X = 33

X = - 3 

Answer 2

6(4x + 2) + 7(-5x + 3) = 66 => 24x + 12 - 35x + 21 = 66 => 24x - 35x = 66 - 12 - 21 => -11x = 33 (-1) => 11x = -33 => x = -33/11 => x = -3.
