To find the solution to the system of equations:
- 7x + 2y = 6
- 8x + y = 3
We can use the substitution or elimination method. Here, let’s use the elimination method for simplicity.
First, we will manipulate the second equation (8x + y = 3) to express y in terms of x:
y = 3 - 8x
Next, we will substitute this expression for y into the first equation:
7x + 2(3 - 8x) = 6
Now, simplify and solve for x:
7x + 6 - 16x = 6
-9x + 6 = 6
-9x = 0
x = 0
Now that we have the value of x, we can substitute it back into the equation for y:
y = 3 - 8(0) = 3
So, the solution to the system of equations is:
(x, y) = (0, 3)
This means that the point (0, 3) is where the two lines represented by the equations intersect on a graph.
