No. An equation must be equal to something, that's why its called an equation. 15x = 60 is an equation, in which case x equals 4
x=100
ln 60 = a
You cannot solve 1 linear equation in 2 unknown variables. You need at least two independent equations.
cos60= 1/2 sin60=1.732/2
15x = 60 The variable is x.
It looks like an incomplete equation.
-53
"Wat" is the variable.
65

60 x 1.5 is 90
Doesn't have integer roots. Quadratic formula gives roots as 3.71 and -5.38.
This is a quadratic expression in x. It cannot be solved because it is an expression: there is no equation to solve. Furthermore, the discriminant for the quadratic = (-10)2 - 4*3*(-5) = 100+60 = 160 which is not a square number. There are, therefore no rational factors. While it would be possible to give irrational factors, factorising a quadratic into linear terms containing irrational numbers is rarely useful.
2 x 30 = 60
x=100
Well, darling, 9 times 6 is 54, not 60. But if you add a little extra spice and multiply 9 by 6.66666666667, you'll get your desired 60. Just don't expect me to stick around for any more math questions, honey.
