Respuesta :
you have to add 4s on both side which cancels -4 in -4s & it makes 9s in to 13s now so the problem looks like this:
26 = 13s now we divide 13 on both side to cancel the 13 in 13s so the answer is :
2 = s
26 = 13s now we divide 13 on both side to cancel the 13 in 13s so the answer is :
2 = s
