Question

Mathematics Solve for me.

Answer 1

x = 2.6

7x+1

Explanation:

If 4.75x = 12.35, what is the value of x?

You need to solve this equation. To do so, we need to isolate the x variable by itself. So, we will divide both sides by 4.75 to get our answer for x.

`4.75x = 12.35\\(4.75x)/(4.75) = (12.35)/(4.75)\\x= 2.6`

x = 2.6

What is 3x+2+4x-1 after combining like terms?

To combine like terms, it means to simplify/merge them together. We know what 1 +2 is? Why write 1 +2, when we can just say 3? That's basically what the question is asking.

Anyway,

`3x+2+4x-1\\`

Merge the x's (DON'T SEPERATE THE X IF ITS BESIDE A NUMBER!!! IT WILL BE MULTIPLIED BY X)

`7x+2-1`

Now simply 2-1.

`7x+1`

Simplified version: 7x+1
