For each equation, explain what you could do first to each side of the equation so that there would be no fractions.

You do not have to solve the equations (unless you want more practice).

1. \(\dfrac{3x-4}{8} = \dfrac{x+2}{3}\)
2. \(\dfrac{3(2-r)}{4} = \dfrac{3+r}{6}\)
3. \(\dfrac{4p+3}{8} = \dfrac{p+2}{4}\)
4. \(\dfrac{2(a-7)}{15} = \dfrac{a+4}{6}\)

Use the distributive property to write an expression that is equivalent to each given expression.

1. \(\text-3(2x-4)\)
2. \(0.1(\text-90+50a)\)
3. \(\text-7(\text-x-9)\)
4. \(\frac45(10y+\text-x+\text-15)\)
