What is the value of x if given x-3 and 2x-8?
If you mean: x-3 = 2x-8 then the value of x works out as 5
When x is -5 what is the value of 2x cubed - 3x?
If the equation is (2x)^3-3x, then the answer is -985. However, if the equation if 2(x)^3-3x, then the answer is -235.
-3 times x -5 equals 2x?
-3(x-5)=2x -3x+15=2x 15=5x x=3
What is the value of x in 2x-5?
In Algebraic Expressions in Algebra,x is a variable,meaning, it has no value. But if you do algebra,like 2x-5, you subtract 2 from 5. The answer is 3,right? but 2 is written before 5,so you write -3. You then can copy the x and voila! That is the answer. BTW the answer is -3x.
What is the Value of 3x - 4 if 2x plus 1 equals -5?
2x + 1 = -5 so 2x = -6 so that x = -3 Then 3x - 4 = 3*(-3) -4 = -9 - 4 = -13
What is the value of x if given x-3 and 2x-8?
If you mean: x-3 = 2x-8 then the value of x works out as 5
Substituiotion method to find the value of y y equals 2x plus 5 x plus y equals 4?
y = 2x+5 x+y = 4 Substitute the value of y into the second equation: x+2x+5 = 4 x+2x = 4-5 3x = -1 Divide both sides by 3 to find the value of x: x = -1/3 Substitute the value of x into the original equations to find the value of y: x = -1/3 and y = 4 and 1/3
What is 4-x2x-5?
If you mean: 4-x = 2x-5 then the value of x is 3
What is the value of x in the equation 6 over x plus 3 over 2x equals 5 over 2?
X=36/X + 3/2X = 5/2 (Multiply both sides by 2X to get x out of the denominator)2X(6/X + 3/2X = 5/2)12+3 = 5X (new equation)5X = 15X = 3
How do you solve 2x plus y equals 8 y equals -x plus 5 substitution method?
2x+y = 8 y = -x+5 Substitute y for -x+5 into the first equation: 2x+(-x+5) = 8 2x-x+5 = 8 x = 8-5 x = 3 Substitute the value of x into the original equations to find the value of y: x = 3 and y = 2
How do you solve for x 2x plus 5 equals 11?
If 2x + 5 = 11, then 11 - 5 = 2x 6 = 2x 3 = x
Find the value of 2x² when x equals 3?

When x equals 5 and y equals 3 by how much does the value of 3x plus 2y exceed the value of 2x plus 3y?
2. If x=5 & y =3 then: 3x + 2y = 3 x 5 + 2 x 3 = 15 + 6 = 21 2x + 3y = 2 x 5 + 3 x 3 = 10 + 9 = 19 ⇒ 3x+2y exceeds 2x+3y by 21 - 19 = 2. Alternatively: 3x+2y exceeds 2x+3y by: (3x+2y) - (2x + 3y) = 3x + 2y - 2x - 3y = x - y If x=5 & y=3 then this becomes: x - y = 5 - 3 = 2
2x-3 equals x plus 5?
2x-3 = x+5 2x-x = 8 x = 8
When x is -5 what is the value of 2x cubed - 3x?
If the equation is (2x)^3-3x, then the answer is -985. However, if the equation if 2(x)^3-3x, then the answer is -235.
Find the value of x if 13 plus 2x equals 3?
13 + 2x = 32x = 3 - 132x = -10x = -5
Evaluate 3x2-2x when x equals 5?
If what you're asking is 3(2)-2x=5? Then, it's 1/2 3(2)-2x=5 6-2x=5 2x=6-5 x=1/2 ================================= Another possibility: I think what he's looking for is the value of (3x2 - 2x) when x=5. It's 3(5)2 - 2(5) = 3(25) - 2(5) = 75 - 10 = 65
