Answer:
g=-x+
Step-by-step explanation:
divide both sides by negative six
=
g=-x+
I don't quite understand the ten strategy, or what EXACTLY you're asking. But, what you can do is when you add a one digit number plus a nine, just change the nine to a ten and subtract one. It is very easy. So, 7+10 equals 17, subtract one and you get 16 which is 7+9. It is always one less than anything plus 10.
Answer:
No they are not equivalent because 3/4 would be equivalent to 6/8, 9/12, 12/16/ 15/20. 16/20 would be the greatest fraction because in its simplest form it would be 4/5.
2x + 4 = 2x + 2
2x - 2x = 2 - 4
0 = -2 ......(when the variables drop out and ur left with an untrue statement, this means there are no solutions)
2x + 5 = 2x + 5
2x - 2x = 5 - 5
0 = 0.....(when the variables drop out and ur left with a true statement, this means there is infinite solutions)
so the two possible solutions when the variables drop out are : no solutions and infinite solutions
