Question

88% 19. What is the solution X in this equation? 2(3x - 7) + 4(3x + 2) = 6(5x+9) + 3

Answer 1

$\\ \sf\longmapsto 2(3x-7)+4(3x+2)=6(5x+9)+3$

$\\ \sf\longmapsto 6x-14+12x+8=30x+54+3$

$\\ \sf\longmapsto 6x+12x-14+8=30x+57$

$\\ \sf\longmapsto 18x+6=30x+57$

$\\ \sf\longmapsto 30x-18x=6-57$

$\\ \sf\longmapsto 12x=51$

$\\ \sf\longmapsto x=\dfrac{51}{12}$
