(3x+2) does this mean 2 3 times??
11 answers
No, (3x+2) means the quantity of 3x plus 2. It is an algebraic expression where 3x is multiplied by 3 and then added to 2.
ok so there is a unknown number that's like being added to 3??
Yes, in the expression (3x+2), the variable x represents an unknown number. The expression shows that this unknown number, when multiplied by 3 and then added to 2.
ok so what about (x +4)??
In the expression (x+4), the variable x represents an unknown number. The expression shows that this unknown number, when added to 4. It is similar to the previous expression, except in this case, x is being added to 4 instead of being multiplied by a coefficient.
so x+4
3x+2
90
what is that?
3x+2
90
what is that?
The expressions "x+4" and "3x+2" are algebraic expressions with variables, while "90" is a constant number.
- "x+4" represents an unknown number (denoted as x) being added to 4.
- "3x+2" represents an unknown number (denoted as x) being multiplied by 3 and then 2 is added to the result.
- "90" is a constant number, which is just 90.
These are different algebraic expressions, each representing a different mathematical operation.

ok but can you put them in like a equation??
Sure! If we want to create equations using the expressions given:
Let's say x represents the unknown number.
- The expression "x+4" can be represented as an equation: x + 4 = y, where y is another value.
- The expression "3x+2" can be represented as an equation: 3x + 2 = z, where z is another value.
- The constant number 90 can be represented as an equation: 90 = w, where w is also a value.
Each of these equations can have different solutions based on the value of x, y, z, and w.

no I meant some like this this type of equation 107°+(4x+5)°=180
Ah, I see what you mean now. Here is an example of an equation:
3x + 2 = 10
In this equation, 3x + 2 is equal to 10. To solve for x, you would need to isolate x by performing the necessary operations to both sides of the equation.
3x + 2 = 10
