Sagot :
4(x + 7) = 38
Since there is no operation sign between the 4 and parenthesis, it makes it an automatic multiplication problem.
You would use distributive property to multiply each which should leave your equation looking like this afterwards:
4x + 28 = 38
(4 times x and 4 times 7)
You would then solve it like a two step equation,
1. +28 - 28 = 0
2. 38 - 28 = 10
4x = 10
10 divided by 4 = 2.5
x = 2.5
We can recheck our work by substituting in the value of x.
4(2.5 + 7) = 38
10 + 28 = 38
When we substituted in the value, it gave us the correct inequality.
Therefore,
x = 2.5

Answer:
x = 2.5
Step-by-step explanation:
Hello!
Let's solve the equation together :)
Solve:
- 4(x + 7) = 38 => Over here, we want to multiply x and 7 by 4, or distribute 4 to both numbers inside the parenthesis.
- 4(x) + 4(7) = 38 =>See how I split the multiplication apart? That's called the Distributive Property
- 4x + 28 = 38 => Simplify. Now subtract 28 from both sides
- 4x = 10 =>Now that we multiply x by 4, we divide both sides to isolate x
- x = 10/4 => Simplify
- x = 2.5
Your answer is x = 2.5
Check:
Plug in 2.5 into our equation
- 4(x + 7) = 38
- 4(2.5 +7) = 38
- 4(2.5) + 4(7) = 38
- 10 + 28 = 38
- 38 = 38
Both sides match so our answer is correct.
