Question

11x+17=10x+13? 3+1,6x=0,1x?​

Answer 1

$\large\sf{}11x + 17 = 10x + 13 \\ \large\sf{}11x + 17 - 10x = 13 \\ \large\sf{}11x - 10x = 13 - 17 \\ \large\sf{}x = 13 - 17 \\ \large\sf{}{\large\boxed{\boxed{  { \large \sf \red{x = - 4 } }}}}$

$\large\sf{}3 + 1,6x = 0,1x \\ \large\sf{}1,6x = 0,1x - 3 \\ \large\sf{}1,6x - 0,1x = - 3 \\ \large\sf{}1,5x = - 3 \\ \large\sf{}{\large\boxed{\boxed{  { \large \sf \blue{x = - 2} }}}}$
