The graph below shows a system of equations:

draw a line labeled y equals minus x plus 5 by joining the ordered pairs 0, 5 and 5, 0. draw a line labeled y equals x minus 1

the x-coordinate of the solution to the system of equations

Step-by-step explanation:

The graph is shown in the image attached.

The given equations are:

The solutions of this system represent the point that both lines have in common, which is also represented in the graph.

Always a system of equations represents the intercepting points between those curves.

Notice that if we multiply one equation by -1, we could eliminate one variable and find the value of the other one:

Then, we replace this value in one equation to find the other value:

Therefore, the solution is the point

So, the x-coordinate of the solution to the system of equations is

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
