"x" always goes on the left side and "y" always goes on the right side of the parentheses. If you only have an "x" then you will just put a zero in for "y" and vice versa. I hope this helps.

How many solutions does an equation have when the variable adds out and the final sentence is true?
salantis [7]

Answer:

Infinitely many solutions

Step-by-step explanation:

If we have a system of equation like:

2x+y=4

6x+3y=12

If we make y the subject in the first equation and substitute into the second equation, we get:

6x+3(4-2x)=12

We expand to get:

6x+12-6x=12

6x-6x+12=12

Now the variable adds out to give:

12=12

This statement is true so the equation has infinitely many solution.

Mr. Vadar washed
saul85 [17]

Answer:

Mr. Vadar washed more than his son.

Step-by-step explanation:

First, you have to make these fractions have an equivalent denomoninator so you can compare them better.

2/7 is the same as 8/28 because you multiply the top and bottom by 4 due to the LCM being 28.

1/4 is the same as 7/28 which you get by multiplying the top and bottom by 7.

7/28 is bigger
