• 
  
• 7x-3/3x+3=5/3 
• CROSS MULTIPLYYYYYYYYYYY!!
• 3(7X-3)=21x-9 |||||| 5(3x+3)=15x+15
• 21x-9=15x+15
• 9+15=24 ||||| 21x-15x=6x
• 6x=24 ,, 24/6=4 X=4!!!!!! 
• BUTUTTUUTUTTTTT HOW MANY SWEETS INITALLU???
• 7x4= 28 ALICE HAS 28
• 3x4= 12 OLIVIA HAS 12!!!

Solving linear equations✅✅✅

• y=mx+c
• (1,5)(2,8) SO x1=1 y1=5 x2=2 y2=8
• Remember , x,y
  
• y2-y1/x2-x-1 = M so
• 8-5/2-1=3/1=3 = m
• y=3x+c , SUBISTUTE IN Y & X ,, 5=3(1)+c 5=3+c,, 5-c=3 ,, c=2
• y=3x+2 

Standard form✅✅
