Answer 2

Let's solve the given equations step by step:

Equation 1: (76x - 40) / 8 + 349 = 420

Step 1: Distribute the division operation (76x - 40) / 8 (76x / 8) - (40 / 8) + 349 = 420

Step 2: Simplify the division 9.5x - 5 + 349 = 420

Step 3: Combine like terms 9.5x + 344 = 420

Step 4: Move 344 to the other side of the equation 9.5x = 420 - 344 9.5x = 76

Step 5: Solve for x by dividing both sides by 9.5 x = 76 / 9.5 x = 8

Therefore, the solution to Equation 1 is x = 8.

Equation 2: (45 + 12x) * 36 - 290 = 6082

Step 1: Distribute the multiplication operation (45 + 12x) * 36 1620 + 432x - 290 = 6082

Step 2: Combine like terms 432x + 1330 = 6082

Step 3: Move 1330 to the other side of the equation 432x = 6082 - 1330 432x = 4752

Step 4: Solve for x by dividing both sides by 432 x = 4752 / 432 x ≈ 11

Therefore, the solution to Equation 2 is x ≈ 11.

To summarize: Equation 1: x = 8 Equation 2: x ≈ 11
