Question

8(x-13)=48; 11x+8x=456; 38x-14x=1608

Answer 1

8(х-13)=48 
х-13=6
х=13+6
х=19

11х+8х=456
19х=456
х=456:19
х=24

38х-14х=1608
24х=1608
х=1608:24
х=67

Answer 2

8х-104=48
8х=48+104
8х=152
х=19

Answer 3

Let's solve each equation step by step:

1. 8(x - 13) = 48

Distribute the 8 to both terms inside the parentheses:

8x - 104 = 48

Add 104 to both sides to isolate the variable:

8x = 48 + 104 8x = 152

Divide both sides by 8 to solve for x:

x = 152 / 8 x = 19

Therefore, the solution to the first equation is x = 19.

2. 11x + 8x = 456

Combine like terms on the left side:

19x = 456

Divide both sides by 19 to solve for x:

x = 456 / 19 x ≈ 24

Approximately, the solution to the second equation is x ≈ 24.

3. 38x - 14x = 1608

Combine like terms on the left side:

24x = 1608

Divide both sides by 24 to solve for x:

x = 1608 / 24 x = 67

Therefore, the solution to the third equation is x = 67.

To summarize:

• The solution to the first equation is x = 19.
• The solution to the second equation is approximately x ≈ 24.
• The solution to the third equation is x = 67.
