It is an equation and the value of x is 1.5
It is an equation and the value of x is -0.7
It is an equation and the value of x is 2
only one value will make the equation true: 2x = 5 x=5/2 x=2.5
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.

It is an equation and the value of x is -0.7
2x+5 = 62 and 3x-y = 23.3 x = 28.5 and y = 62.2 Solve the first equation and then substitute the value of x into the second equation to find the value of y.
It is an equation and the value of x is 2
2x + 5 = 25 2x = 20x = 10
only one value will make the equation true: 2x = 5 x=5/2 x=2.5
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
It appears to be a simple linear equation in 'x'. But it has no solution. There is no numerical value for 'x' that can make it a true statement.
It is a linear equation in x. The equation has the solution x = 0.
If 3x = x + 10 then 2x = 10 and x = 5
Using the quadratic equation formula the value of x is -8 or 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
