Solve for x: 13(6x – 5) – x = 13 – 2(x + 1)
In this article, we will solve for x in the equation 13(6x – 5) – x = 13 – 2(x + 1).
Step 1: Expand the Left Side of the Equation
First, let's expand the left side of the equation:
13(6x – 5) = 13(6x) – 13(5) = 78x – 65
So, the equation becomes:
78x – 65 – x = 13 – 2(x + 1)
Step 2: Simplify the Left Side of the Equation
Now, let's simplify the left side of the equation:
78x – x = 77x 77x – 65 = 13 – 2(x + 1)
Step 3: Expand the Right Side of the Equation
Next, let's expand the right side of the equation:
13 – 2(x + 1) = 13 – 2x – 2 = 11 – 2x
So, the equation becomes:
77x – 65 = 11 – 2x
Step 4: Add 2x to Both Sides of the Equation
Now, let's add 2x to both sides of the equation:
77x + 2x – 65 = 11 79x – 65 = 11
Step 5: Add 65 to Both Sides of the Equation
Next, let's add 65 to both sides of the equation:
79x = 11 + 65 79x = 76
Step 6: Divide Both Sides of the Equation by 79
Finally, let's divide both sides of the equation by 79:
x = 76/79 x = 48/79
Therefore, the value of x is 48/79.
Conclusion
In this article, we have solved for x in the equation 13(6x – 5) – x = 13 – 2(x + 1) and found that x = 48/79.
