Math Problem Statement

Solve for x: 5(2x - 5) - 4x - 4 = -11

Solution

Let's solve the equation given in the image:

5(2x5)4x4=115(2x - 5) - 4x - 4 = -11

Step 1: Distribute the 5

52x=10x5 \cdot 2x = 10x 5(5)=255 \cdot (-5) = -25 Now the equation becomes: 10x254x4=1110x - 25 - 4x - 4 = -11

Step 2: Combine like terms

(10x4x)=6x(10x - 4x) = 6x (254)=29(-25 - 4) = -29 This simplifies the equation to: 6x29=116x - 29 = -11

Step 3: Add 29 to both sides

6x29+29=11+296x - 29 + 29 = -11 + 29 6x=186x = 18

Step 4: Divide both sides by 6

x=186=3x = \frac{18}{6} = 3

Solution:

x=3x = 3
