3x actually means 3 * x.So we are going to follow BODMAS rule...
3x-5-10
=3*4-5-10
=12-5-10
=7-10
=-3
Here's your answer..
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
5
The idea is to replace "x" by "1.7" in this case, then do all the indicated calculations.
3x+4=10 To solve: 3x+4=10 3x=6 x=2
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.

explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
When x = 2, 3x + 5 = 11.
the answers is d
To simplify the expression (3x - 10 - 37), combine the constant terms (-10) and (-37). This results in (3x - 47). So, the simplified expression is (3x - 47).
Given a value of x, find the value for -3x + 2
When you have an algebraic expression with variables in it, you need to know the the value of each variable. The value of the expression is found by replacing the variables with their values and simplifying. For example, evaluate 2xy-3x if x=5 and y=-1. 2xy-3x = 2*5*(-1) -3*5 = -10-15 = -25.
The algebraic expression that represents the sum of 10 and 3 times a number x is 10 + 3x. This expression can be simplified by multiplying 3 with x to get 3x, and then adding 10 to it. In this expression, 3x represents three times the value of x, and 10 represents a constant value added to the product of 3 and x.
In math evaluating is where you simplify an expression as much as possible. For example to evaluate 5+2 you simplify it so it is 7. To evaluate 5x+3x+4y you simplify it to 8x+4y.
The expression 3x + 2 represents the sum of three times a variable x and the constant 2. This is an algebraic expression that can be simplified by combining like terms. To evaluate this expression, you need a specific value for x.
