Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
Answer:
95
Step-by-step explanation:
step 1
Find out the total ball bearing ordered
Multiply the number of ball bearing boxes by the number of ball bearings in each box.

step 2
Find out the total springs ordered
Multiply the number of spring boxes by the number of springs in each box.

step 3
To find out how many more ball bearings than springs did they order, subtract the total number of springs from the total number of ball bearings

Answer:
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
Step-by-step explanation:
We need to solve the linear system of equations.

We can write second equation y=x-4 as: 
Let:

Now, Adding equation 1 and 2

So, we get x = 1
Now, put value of x in second equation to find value of y:

So, we get y = -3
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
