Answer 3

To solve each equation, we'll simplify the expressions and isolate the variable "x" on one side of the equation. Let's solve each equation step-by-step:

1. 2(5x + 11) = 52

Step 1: Distribute the 2 on the left side of the equation: 10x + 22 = 52

Step 2: Subtract 22 from both sides to isolate 10x on one side: 10x = 30

Step 3: Divide both sides by 10 to find the value of x: x = 30 / 10 x = 3

So, the solution for the first equation is x = 3.

2. 4(x - 3) = 8

Step 1: Distribute the 4 on the left side of the equation: 4x - 12 = 8

Step 2: Add 12 to both sides to isolate 4x on one side: 4x = 20

Step 3: Divide both sides by 4 to find the value of x: x = 20 / 4 x = 5

So, the solution for the second equation is x = 5.

3. 10(2x + 1) = 50

Step 1: Distribute the 10 on the left side of the equation: 20x + 10 = 50

Step 2: Subtract 10 from both sides to isolate 20x on one side: 20x = 40

Step 3: Divide both sides by 20 to find the value of x: x = 40 / 20 x = 2

So, the solution for the third equation is x = 2.

4. 3(5x - 4) = 33

Step 1: Distribute the 3 on the left side of the equation: 15x - 12 = 33

Step 2: Add 12 to both sides to isolate 15x on one side: 15x = 45

Step 3: Divide both sides by 15 to find the value of x: x = 45 / 15 x = 3

So, the solution for the fourth equation is x = 3.

In summary: x = 3 (for the first equation) x = 5 (for the second equation) x = 2 (for the third equation) x = 3 (for the fourth equation)
