Math Problem Statement

-5(4x+11)-5=50

Solution

Let's solve the equation step by step:

Given equation:
5(4x+11)5=50-5(4x + 11) - 5 = 50

Step 1: Distribute 5-5 across the parentheses.

54x=20x-5 \cdot 4x = -20x 511=55-5 \cdot 11 = -55 So, the equation becomes: 20x555=50-20x - 55 - 5 = 50

Step 2: Combine like terms on the left side.

20x60=50-20x - 60 = 50

Step 3: Add 60 to both sides to isolate the term with xx.

20x=50+60-20x = 50 + 60 20x=110-20x = 110

Step 4: Divide both sides by 20-20 to solve for xx.

x=11020x = \frac{110}{-20} x=112x = -\frac{11}{2} x=5.5x = -5.5

So, the solution is: x=5.5x = -5.5
