Practice problem
Which of the following are equivalent to: 3x+15=20\frac{3}{x} + 15 = 20x3+15=20
x3+15=120\frac{x}{3} + 15 = \frac{1}{20}3x+15=201
3x=20−15\frac{3}{x} = 20 - 15x3=20−15
x=3÷(20−15)x = 3\div (20-15)x=3÷(20−15)
x=(20−15)÷3x = (20-15)\div 3x=(20−15)÷3
Type a concept, like “slope” or “photosynthesis”.
