Answer:
4y = -m-1 bcoz u use the formula y-y1 = (y2-y1/x2-x1) times (x-x1)
 
        
             
        
        
        
14+2x=4x: divide 2x on each side
14=2x: divide by 2
7=x

Answer: 8 weeks 
explanation: 125 + 15x = 245 
You then have to subtract 125 from both sides so we can isolate our variable which will give us 15x = 120 . Divide 15 from both sides : 15x/15 = 120/15 which will give us x = 8.
