Answer:
ok i see that question it would be 3
Step-by-step explanation:
Answer:
In step 2, he needed to divide both sides of the equation by 5
Step-by-step explanation:
we have
Solve for a------> That means isolate the variable "a"
step 1
Subtract 2b to both sides
step 2
Divide by 5 both sides
Answer:
(x, y) = (0, -2248)
Step-by-step explanation:
<u>Substitution</u>
Substitute for y:
300x -2248 = 350x -2248
0 = 50x . . . . . . . . add 2248-300x to both sides
x = 0
y = 300·0 -2248
The solution is (x, y) = (0, -2248).
__
<u>Elimination</u>
Subtract the first equation from the second.
(y) -(y) = (350x -2248) -(300x -2248)
0 = 50x
x = 0
y = 300·0 -2248
The solution is (x, y) = (0, -2248).

<em>Additional comment</em>
If you think for a bit about what the graph looks like, you realize both lines cross at their y-intercept, (0, -2248). That point of intersection is the solution to the system of equations.
