    its so simple 5y-8y=12 -3y=12 y=-4

    Does that make sense? So he took the 5y minus the 8y and he got 12y

    add 6 on both the side as the result on hand +6-6 would be cancel and other side +6+6 add to give 12

    i see where you got the 12 in that equation. my next one has two different numbers on each end where the 6 would have been . 4a-10=3a-1

    same here as we done in previous one 4a-10=3a-1 add +10 on the sides we get' 4a-10+10=3a-1+10 now' -10+10=0 nd -1+10=9 4a=3a+9 again'subtract -3a on both sides 4a-3a=3a-3a+9 we get' a=9 becoz 3a-3a=0

    4a-10=3a-1 The idea is to get 'a' by itself. First, let's put the "10" and the "1" numbers on the same side. so, add 10 to both sides. 4a-10 = 3a-1 +10 +10 which gives 4a= 3a-1+10 simplified to: 4a= 3a+9 Now we want to moves the a's to the same side, but not the one that we moved the 10 to. 4a= 3a+9 So, let's subtract 3a from both sides: 4a= 3a+9 -3a -3a 4a - 3a = 9 simplifies to a = 9 sorry, I type a little slow :)

    Yes, that works. Good to show where the 3a cancels and the 10 cancels

    i'll assume it is -3 6y-17=-3-y add 17 6y=-3-y+17 6y=-y+14 ok so far?

    then, add y 6y+y=14 7y = 14 y=2 Blossom_red's method works too :)

    You can check your work by plugging the number you end up with back into the equation Substitute the r for the 2: 2r+10=18-2r 2(2)+10=18-2(2) 4+10=18-4 14=14 = true, so it was right :) Sure ! :)
