It equals to the equation of a straight line.

The equation seems to equal 72.

That is not a correct equation. The numbers on the left equal -16, not 0. This is an equation with no solution.

The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.

It's not an equation and therefore unsolvable until it equals something.

r = 4

x = -3

In the equation 3x plus 7 equals 13, x is equal to 2.

The equation soild plus gas equals a liquid

Yes that is correct

That is called an equation. Any time a certain amount of numbers equals another number, that is called an equation. This is a perfect example of one, as 10 does in fact equal 10.

Technically there are no variables in this equation, as 47 minus 25 is equal to x (22)

y= 131127.691.

The x-intercept is equal to -b/m.

The equation ax2 + bx + c = 0, where a != 0 is called quadratic.

Multiply the first equation by 3 to give 9x + 15y = 21

This equation is not possible. Two plus three plus four plus five does not equal 287. The system has no solution.

Ten. That means 3x equals 30, and 30 divided by three is ten.

It equals a simple linear equation in 'y'. Its solution is 7/3 .

Equals anything... x is a variable. If that equation was set equal to zero then you could solve for x, but that is not what you have asked.
