Answer:
{(12-4) + (15-8)}x = 65
Step-by-step explanation:
The amount Amber earns per week
12-4
The amount Nathan earns per week
15 -8
The total amount per week they earn together
(12-4) + (15-8)
Multiply by x weeks
{(12-4) + (15-8)}x
Set this equal to 65 to be the amount they need to equal 65 dollars
{(12-4) + (15-8)}x = 65
28 + (3x -2) + 28 = 6x
28+ (3x -3x -2) + 28 = 6x - 3x
28+ (-2) + 28 = 3x
28 - 2 + 28 = 3x
26 + 28 = 3x
54 = 3x
18 = x
Answer:
Consider the system of equations,
and 
As we know that,
'The intersection points of the graphs of the system of equations are the solutions of the system of equations'.
So, after plotting the given graphs, we see that,
The only intersection point is (0.714,-2.857).
Thus, the solution of the system is x= 0.714 and y= -2.857.
