77+72=149 
149/2=74.5 
through the process of elimination, I found that Jim needs to get an 88 or higher to receive an average of 79 or greater. 

77+72+88=237 
237/3=79

What is the solution for this system of equations y = x - 4 Y = -x + 6
lana66690 [7]

Our system of equations is:

y = x - 4

y = -x + 6


We can solve this system of equations by substitution. We already have one equation solved for the variable y in terms of x, so we can substitute in this equivalent value for y into the second equation as follows:


y = -x + 6

x - 4 = -x + 6


To simplify this equation, we first are going to add x to both sides of the equation.


2x - 4 = 6


Next, we are going to add 4 to both sides of the equation to separate the variable and constant terms.


2x = 10


Finally, we must divide both sides by 2, to get the variable x completely alone.


x = 5


To solve for the variable y, we can plug in our solved value for x into one of the original equations and simplify.


y = x - 4

y = 5 - 4

y = 1


Therefore, your final answer is x = 5 and y = 1, or as an ordered pair (5,1).


Hope this helps!
