Answer:
x = 2.6
7x+1
Step-by-step 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.
[tex]4.75x = 12.35\\\frac{4.75x}{4.75} = \frac{12.35}{4.75}\\x= 2.6[/tex]
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,
[tex]3x+2+4x-1\\[/tex]
Merge the x's (DON'T SEPERATE THE X IF ITS BESIDE A NUMBER!!! IT WILL BE MULTIPLIED BY X)
[tex]7x+2-1[/tex]
Now simply 2-1.
[tex]7x+1[/tex]
Simplified version: 7x+1
