What is 7 plus x equals 2x?
x+7 = 2x 2x = x+7 2x-x = 7 x = 7
If 2x plus 2x equals 40 what does x equal?
To solve for x, set up the equation: 2x +2x = 40 (then simplify) 4x = 40 (then divide both sides of the equation by 4) x = 10 (this is the answer)
What is the answer for this equation 2x-3 equals x plus 2?
2x-3=x+2 2x-x=2+3 x=5
In the equation 2x plus 28 what is the value of x?
If you mean 2x = 28 then the value of x is 14
How do you solve this equation - 9 - 2x plus x equals - 13?
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
What is 7 plus x equals 2x?
x+7 = 2x 2x = x+7 2x-x = 7 x = 7
If 2x plus 2x equals 40 what does x equal?
To solve for x, set up the equation: 2x +2x = 40 (then simplify) 4x = 40 (then divide both sides of the equation by 4) x = 10 (this is the answer)
What is the answer for this equation 2x-3 equals x plus 2?
2x-3=x+2 2x-x=2+3 x=5
What is the solution of the equation 2x - 2 ( x - 1 ) = 2x + 1?
x = 1/2
Find positive root of equation x3 equals 2x plus 5?
x^3=2x+5 x^3-2x-5=0 Graph the equation or use a calculator. x= 2.09455148
Solve the equation for x 2x 3x -4 18?
2x + 3(x -4) = 18
In the equation 2x plus 28 what is the value of x?
If you mean 2x = 28 then the value of x is 14
How do you solve this equation - 9 - 2x plus x equals - 13?
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
What is the value of x in the equation 2 plus 2x equals 18?
2 + 2x = 18 2x = 18 - 2 2x = 16 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.
How do you solve for x on both sides of the equation?
You add or subtract some quantity on both sides of the equation, so that you only have "x" on one side of the equation. Example: 4x + 3 = 2x - 5 Subtract 2x on each side, this leaves you: 4x - 2x + 3 = 2x - 2x -5 2x + 3 = -5
What is the difference between equivalent expressions and equivalent equations?
An expression does not equate to anything. An equation is equal to something. Expression: x+2 Equation: x+4=2x Equivalent expressions: x+2 and 2x-2 if x=4 Equivalent equations: x+4=2x and -x+10=2x if x=4
