This equation does not equal a number, but it can be factorised.
x2-xy-20y2=(x-5y)(x+4y)
only when x is equal to 2
it means that x should equal 10. x + x = 20. x = 10
2 x 7 x 7 is equal to 98.
An expression that may or may not be equal is one that contains variables, such as ( x + 2 ) and ( 3 ). Depending on the value of ( x ), these two expressions can either be equal or unequal. For example, if ( x = 1 ), then ( x + 2 = 3 ), making them equal, but if ( x = 0 ), then ( x + 2 = 2 ), which is not equal to 3.
-x + x = 0.
It is equal to zero.
It depends what x is equal to.
sin(x) = tan(x) when x equal 0
only when x is equal to 2
2 x 4 x 8 x 10 is equal to 640.
If: 75/x = 25 Then: x = 3
it means that x should equal 10. x + x = 20. x = 10
If: x-6 = -8 then x = -2
7.86 X 4.6 is equal to 36.156.
2 x 7 x 7 is equal to 98.
4 x 7 x 5 is equal to 140.
7 x 7 x 7 is equal to 343.
