6x+5k=12
-1
Without an equality sign it can't be considered to be an equation
It is a linear expression in one variable, x. It is not an equation and so cannot be solved. It can be simplified to -6x-27.
It is a linear equation in the single variable,x, which is equivalent to x = -18

Well, f(x) = 6x + 9 is a function of x {it passes the vertical line test}. but y = 6x + 9 is an equation {linear equation of two variables}

3x=6x-15 ....you want to take 6x and put it on the other side of the = sign. To do that you do the opposite. So you would subtract since 6x is a positive number. so then the equation is 3x-6x=-15. 3x-6x = -3x which makes the equation -3x=-15. Then you would take -3 which is being multiplied by x and do the opposite operation on the other side. so -3 divided by -15 equals 5. which makes the equation now x=5. So then 5+8=13
It's a linear equation in 'x'.It has exactly one solution.Here's how to find it:-6x = 30Divide each side by -6:x = -5
