4+3x = four increased by three x

3x-4 = three x decreased by four

2(x+3) = two times the quantity of x increased by three

5+1/3x = five increased by one third x

3x-4 = three x decreased by four

2(x+3) = two times the quantity of x increased by three

5+1/3x = five increased by one third x

3x-4= three ex minus four

2(x+3)= two times the quantity of ex plus three

5+1/3x= five plus one third ex
