Ayyee. It's Mickayla here, and ill be walking you through 3 equations we did on pg.44 :)

~~but being honest here you should have these questions "in the bag" but.~~

(if you're actually here for help on two step equations, hope this kinda helps.)

#5) -7y + 2 = -75 - first make sure you have it in order (coefficient/variable, constant and answer)

-7y + 2 - 2 = -75 -2 - second, isolate the variable

(make sure you do it on both sides so its balanced)

-7y = -77 - afterwards you are left with the coefficient, variable and "answer"

-7y = -77 - next you would have to get rid of the -7 -7 coefficient (by dividing on both sides)

y = +11 - and you're answer should be +11 :)

#6) v - 10 = -14 - this question would also follow the first questions steps

v - 10 + 10 = -14 + 10 - isolate the variable on each side.

v = -4 - now you would have to get rid of the

3 coefficient.

(3) v = (3) -4 - instead of dividing like the last questions,

3 you would have to multiply on both sides.

v = -12 - and the answer is should be -12 :D

#11) 45 = 6d - 45 - as you can see this question is not in "order"

45 = 6d - 45 -that means you would have to rearrange them. (just to make it easier for yourself)

6d - 45 = 45 -if you have rearranged them correctly, you would have a question like this.

6d - 45 + 45 = 45 + 45 - and now like the other two questions, isolate the variable.

6d = 90 - and if you added correct likely (which i hope you did) you'd end up with 6d = 90

6d = 90 - now just like the first question, you have to get

6 6 rid of the coefficient by dividing on both sides.

d = 15 - and your answer should be +15 :P

and with two step problems you can do some "right side" problem solving. some might think its difficult, and others might think its a walk in the park, feel free to do which ever way works for you. :)

and if you still have a hard time doing two step algebra equations, feel free to watch this video about two step algebra equations :)))

P.S make sure you verify as well! and happy halloween !!1!
