When solving an equation, you must do the same thing to both sides or else it won't be equal
when dealing with one unknown (x) try to get the unknown on one side
2(x-3)=1.2-x distribute or multiply 2 by x then -3
so (2 times x)+(2 times -3[remember negative times positive=negative]) 2x-6=1.2-x add 6 to both sides 2x=7.2-x add x to both sides 3x=7.2 divide both sides by 3 x=2.4
5. the equation looks like: ((2x+1)+4)/((x)+4)= 5/3 then you do cross multiplication and get: 6x+3+12=5x+20 subtract 5x on each side. subrtract the 3 and 12 from the 20. and you get your answer 5=x
