How do you solve # ( x+12 )/( x-4 ) = ( x-3 )/( x-7 ) #?
First, we'll cross multiply: if
Add 84 to both sides and simplify
Divide both sides by 12 and simplify
To solve this, we use cross multiplication:
Based on this, in this case you would do:
And now we just expand and simplify:
Combine like terms:
Divide both sides by
