We have :

 

2 + .70x = ..75(x + 2)     whhere x is the number of pounds of the 70% mix

 

Simplify

 

2 + .70x = .75x + 1.5     subtract 1.5, .70x from both sides

 

.5 = .05x       divide both sides by .05

 

.5 / .05  =  x =  10 lbs of the 70% mix

 

And (x + 2)   = (10 + 2)  = 12 lbs. total
