1. The expressions are already simplified.
2. Cross multiply, i.e. multiply the numerator of the left side by the denominator of the right side = the
numerator of the right side multiplied by the denominator of the left side.

3x=4x+4

Move the variables to the left side and the constants to the right side by using inverse operations.

Subtract 4x from both the sides.

3x4x=4

x = 4 or x = 4.

x ≥ 4
Multiplying both the sides with 1, x ≤ 4.
