Answer 3

To solve the equation 7(3x+26)+84=413, follow these steps:

Step 1: Distribute the 7 on the left side of the equation:

7 * 3x + 7 * 26 + 84 = 413

Step 2: Simplify the left side:

21x + 182 + 84 = 413

Step 3: Combine the constants on the left side:

21x + 266 = 413

Step 4: Isolate the variable term (21x) on one side. To do this, subtract 266 from both sides of the equation:

21x = 413 - 266

Step 5: Calculate the right side:

21x = 147

Step 6: Finally, isolate x by dividing both sides by 21:

x = 147 / 21

Step 7: Simplify the right side:

x = 7

So, the solution to the equation is x = 7.
