There are four ways that a system of equations can be solved: graphing, substitution, elimination, or using Cramer’s Rule.

but what are the differences?
I can you simply explain how to do these types of problems?

y = 1n (x+3)
x = 1n (y +3)
e^x = y + 3 <--- this is the part i dont understand
e^x - 3 = y

like what rule or defintion allows this step. how come when you put e^x, the 1n disappears? help please, im so confused. i want to understand.

Objects of masses m1 = 4.00 kg and m2 = 9.00 kg are connected by a light string that passes over a frictionless pulley . The object m1 is held at rest on the floor, and m2 rests on a fixed incline of = 40.0°. The objects are released from rest, and m2 slides 1.00 m down the incline in 4.00 s.

a) Determine the coefficient of friction between m2 and the incline.

b) determine the tension in the string
