Answer:
x=1
Step-by-step explanation:
For this problem, we can choose to eliminate either the x values or the y values.
In this case, it would be easier to do y.
We alter the first equation by multiplying by -2 on both sides.
-4x+-6y=-16
Now, we have the equations
-4x+-6y=-16 and 5x+6y=17.
We can see that there is -6y in one equation and 6y in the other, meaning that if we add both equations together, the ys will cancel each other out because they are opposites.
So let's add the equations.
-4x-6y+5x+6y=-16+17
x=1

Answer:
a.
and 
Step-by-step explanation:
Let x be the larger number and y be the smaller number.
We have been given that one number is 4 more than another. We can represent this information in an equation as:

We can manipulate this equation as:


We are also told that the sum of both numbers is 60. We can represent this information in an equation as:

Upon looking at our given choices, we can see that option 'a' is the correct choice.
