pls help me with this if you know it also to explain it thanks Solve the equation -21 + 70n = 77 for n.
gogolik [260]

Answer:

n = 1 2/5

-21 + 70n = 77

Add 21 to each side

-21+21 + 70n = 77 +21

70n = 98

Divide each side by 70

70n/70 = 98/70

n =98/70

n = 70/70 +28/70

n = 1 + 2/5

n = 1 2/5
