To solve the system of equations, we can use the method of substitution.
Step 1:
We have two equations:
1) y = -1/2x + 6
2) y = 3x - 1
Since both equations are equal to y, we can set them equal to each other:
-1/2x + 6 = 3x - 1
Step 2:
To get rid of the fractions, let's multiply every term in the equation by 2:
-2(1/2x) + 2(6) = 2(3x) - 2(1)
Simplifying:
-x + 12 = 6x - 2
Step 3:
Let's solve for x by adding x to both sides and subtracting 12 from both sides:
-x + x + 12 = 6x + x - 2 + 12
Simplifying:
12 = 7x + 10
Step 4:
Next, subtract 10 from both sides:
12 - 10 = 7x + 10 - 10
Simplifying:
2 = 7x
Step 5:
Finally, divide both sides by 7 to solve for x:
2/7 = 7x/7
Simplifying:
x = 2/7
Step 6:
To find the value of y, substitute the value of x back into one of the original equations. Let's use the second equation:
y = 3(2/7) - 1
Simplifying:
y = 6/7 - 1
Step 7:
To subtract fractions, we need to have a common denominator. In this case, it is 7. So let's write 1 as 7/7:
y = 6/7 - 7/7
Simplifying:
y = -1/7
Step 8:
Therefore, the solution to the system of equations is x = 2/7 and y = -1/7.
