It’s A i did the test myself..
Answer: 1.) x - 2y = 4 , add 2y to both sides. ---> answer is, X = 2y + 4
2.) 2x - 6y = 8, Add 6y to both sides, then divide both sides by 2. --> answer is, X = 3y + 4
Let's first start off by making 2/10 the same denominator as 5/100. To do this you would need to multiply both sides of the fraction by 10. You wild end up with 20/100. Now we worry about the striped fish. There are 5/100 striped fish, since we have the same denominator we can add them together!
20+5=25
25/100 is reduced to 1/4!
5,000-500-50-5 they are not all the same value.
