Rearrange the equation so q is the independant variable: -7q+12r=3q-4 r=

r =

Step-by-step explanation:

In order to make 'q' the independent variable in the equation, you need to solve for 'r'.  The dependent variable would be 'r' because it depends on the value of 'q' to be solved.  We can solve for 'r' by using inverse operations and completing the same operation on both sides of the equation. Starting with the initial equation and solving for 'r':

-7q + 12r = 3q -4

Add '7q' to both sides:  -7q + 7q + 12r = 3q - 4 + 7q  or 12r = 10q - 4

Divide all terms by 12:  12r/12 = 10q/12 - 4/12

Simplify:  r =

the answer is 8/21

hope this

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4
