X=7
I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
x^3=2x+5 x^3-2x-5=0 Graph the equation or use a calculator. x= 2.09455148
2x-3 = x+5 2x-x = 8 x = 8
This question can only be answered with additional information, such as the value of x.Given x = 3, 2x * 4 = 2(3) * 4 = 6 * 4 = 24Given x = 5, 2x * 4 = 2(5) * 4 = 10 * 4 = 40------------------------------------------------------------------------------------------------------------------Contrary to the answer above; 2x * 4 = 8x
13 + 2x = 32x = 3 - 132x = -10x = -5
6
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
2x + 3 = 6 2x = 3 x = 3/2 = 1.5
2x+3=9 2x=9-3 2x=6 2x/2=6/2 X=3
It is an equation and the value of x is 6.5
3x - y = 3y = 2x + 2Put the value of y in the 1st equation:3x - y = 3 it will be -->3x - ( 2x + 2 ) = 33x - 2x - 2 = 3x - 2 = 3X = 5Put the value of X in the 2nd equation so as to find the value of Y :y = 2x + 2y = 2(5) + 2y = 10 + 2Y = 12
2x+3=9 Your question is what is X value. 2x+3=9 2x=9-3 2x=6 2/2x=6/2 x=3 Best answer by Deo Math Club...
If 3x + 3 = 2x + 6 then 3x - 2x = 6 - 3 x = 3
7(2 + 2x) is 78 when x = 3. = 5,764,801.
2x+3y = 6 2x+3(0) = 6 2x = 6 x = 6/2 x = 3
Do you mean 8 = 2x-3 and that x = 5 and a 1/2 The equation can be also set out as: 2x-3 = 8 Add 3 to both sides to keep the equation in balance: 2x-3+3 = 8+3 2x = 11 Divide both sides by 2 to find the value of x: x = 5 and a 1/2 or 5.5 as a decimal
