Step 1. Subtract the 6y-9y which will give you -3y-4
Step 2. Add 4 to both sides, which will give you -4y = -2y +2
Step 3. Add 2y to the other side, which will
Give you -2y = 2
Step 4. Divide both sides by -2, which will give you -1
You can't show work easily on here. So i'll try. 5 times 5 is 25, put down the 5 and carry the 2 5 times 3 is 15, plus 2 17, put 7 carry the 1. 5 times 1 is 5 plus 1 is 6. so so far you have 675. Now for 2. 2 times 5 is 10, put 0 carry the 1, 2 times 3 is 6 plus 1 is 7 put 7, 2 times 1 is 2 put 2, so now you have 270. Aline the numbers in a way where the 0 of 270 is under the 7 of 675. Add together. You have 945.
