​Solve the following

​1) Identify the inverse operation





2) Do the inverse operation to BOTH SIDES of the equation.

Fill in the Blanks

$-3x=6.3$

Fill in the Blanks

3x = -27

Fill in the Blanks

$18=0.3b$

​Solve the following

​1) Identify the inverse operation





2) Do the inverse operation to BOTH SIDES of the equation.

Fill in the Blanks

$\frac{x}{15}=3.5$

Fill in the Blanks

$12\ =\ \frac{a}{-4}$  

Fill in the Blanks

$1.5=\frac{x}{3.6}$

Another type of division problem

​FIRST you need to get the variable OUT of the denominator!!

1) multiply BOTH SIDES by the variable


2) solve as usual

Fill in the Blanks

$\frac{68}{x}=340$

Fill in the Blanks

$\frac{8}{x}=64$
