ayuda tengo un trabajo demasiado largo para mañana necesito saber cuales de las siguientes parejas de ecuaciones son equivalentes .
a. 3×-5=10
b. -7×+8=5
c. -15×+50=5
d. 10+3×-1=0
e. 8×+7=5
f. 7×+8=5
g. 50+15×=5
h. 48×+42=30
i. 3×+5=-4
j. -5-3×=4
k. 8-7×=5
l. 15 ×-50=-5
necesito tambien q me ayuden a solucionar las siguientes ecuaciones
a.35a-83=-13
b.81b+15=-471
c.45c-73=-28
d.-27d+18=72
e.72e+72=0
f. 83f-51=-51
g.-42g-150=-24
h.73h-90=202
